Inside your routine

What you actually get

Evidence-first actives

Minoxidil, ketoconazole, rosemary oil, peptides and caffeine ranked by what the evidence supports for your pattern of loss.

Wash-day structure

How often to wash, what to use on scalp versus lengths, and where a bond builder or protein step belongs.

Prescription hand-off

When finasteride, dutasteride or a dermatologist workup is the honest answer, Aura says so and points to telehealth options.

Progress tracking

Log check-ins over months so you can see whether shedding slowed before deciding to switch.

Every hair routine is generated from your own intake — goals, biology, budget and preferences. Start your intake or read how credits and usage work before you subscribe.

Hair loss products are noisy — Aura filters

Most hair growth marketing rests on thin or no evidence. Aura separates the ingredients with real clinical support from the ones selling hope, and tells you plainly which category each product is in.

Texture-aware, not one-size-fits-all

Routines account for hair texture, porosity, density and chemical history, so a 4c wash-day plan looks nothing like a fine straight-hair plan.

Realistic timelines

Hair moves slowly. Aura sets expectations in months, not weeks, and flags the shedding phase that makes people quit treatments too early.

Hair and scalp ingredients explained

Hair care has more folklore than almost any other wellness category, partly because results take months to show and partly because the strongest treatments require a prescription. Here is the honest read on what actually changes hair growth, breakage and scalp health, and what mostly changes marketing copy.

Minoxidil (topical, 5% foam or solution)

Widens blood vessels around the follicle and extends the growth phase of the hair cycle, prompting miniaturised follicles to produce thicker, longer strands.

Best for
Pattern hair loss (androgenetic alopecia) at the crown or diffusely, in both men and women.
Evidence
Strong. Decades of trial data support regrowth in a meaningful proportion of users, though results vary and roughly a third see little change.
Good to know
Available over the counter. Needs twice-daily use for at least 4 months before judging it, and shedding stops if you stop using it. Expect a temporary increase in shedding in the first 2–6 weeks — that is old hairs being pushed out, not a bad sign.

Finasteride (oral, prescription only)

Blocks the enzyme that converts testosterone into DHT, the hormone most responsible for shrinking genetically susceptible follicles.

Best for
Pattern hair loss in men with a hormonal component; not appropriate for most women, especially anyone who is or may become pregnant.
Evidence
Strong for slowing and partially reversing loss in men, but it is a prescription medicine with a real, if uncommon, side-effect profile including sexual side effects. This is not an over-the-counter or DIY decision.
Good to know
Aura will flag this as a routine to raise with a licensed prescriber, not something to self-source online. Never share pills or use partners' unused prescriptions.

Ketoconazole (shampoo, 1–2%)

An antifungal that reduces Malassezia yeast on the scalp, calming the inflammation behind dandruff and seborrhoeic dermatitis, with some evidence of a mild independent effect on hair density.

Best for
Flaking, itching and greasy scalp irritation, often used alongside minoxidil.
Evidence
Good evidence for dandruff and seborrhoeic dermatitis; the hair-growth effect is smaller and less certain than minoxidil's.
Good to know
1% is available over the counter in most markets; 2% is often prescription strength. Leave on the scalp for 3–5 minutes before rinsing — most people rinse it out too fast to work.

Rosemary oil

Thought to improve local circulation and has mild anti-inflammatory compounds, though the mechanism in human scalps is not well mapped.

Best for
People wanting a gentler, non-prescription addition to a regrowth routine, or who cannot tolerate minoxidil.
Evidence
Promising but thin. One small trial found it roughly comparable to 2% minoxidil over 6 months, but the study was small and hasn't been widely repeated. Treat it as a low-risk add-on, not a replacement for treatments with a larger evidence base.
Good to know
Dilute in a carrier oil before scalp contact — undiluted essential oil can irritate. Patch test first.

Caffeine and peptide complexes

Marketed to stimulate follicle cells and block DHT activity at the scalp surface, based mostly on cell-culture and small manufacturer-funded studies.

Best for
Anyone who wants a low-commitment leave-in alongside a proven treatment, without expecting it to carry the routine alone.
Evidence
Weak. Lab data looks encouraging, but independent, well-powered human trials are scarce. Worth trying as an add-on, not worth paying a premium for.
Good to know
If a product's whole pitch is caffeine or peptides with no minoxidil in the formula, treat the growth claims with real scepticism.

Bond-building treatments (e.g. bis-aminopropyl diglycol dimaleate)

Chemically reforms broken disulphide bonds inside the hair shaft that are damaged by bleach, heat and chemical services, restoring some elasticity and reducing breakage.

Best for
Chemically lightened, permed or heat-damaged hair that snaps or feels straw-like.
Evidence
Reasonably good evidence for measurable strength and breakage reduction in damaged hair; little relevant benefit for virgin, undamaged hair.
Good to know
Works best paired with a colourist-applied version at the time of bleaching, with an at-home maintenance version between salon visits.

Zinc pyrithione and salicylic acid (scalp exfoliants)

Zinc pyrithione has antifungal and antibacterial action similar to ketoconazole; salicylic acid dissolves the oil and dead-skin buildup that traps flakes against the scalp.

Best for
Flaking without significant inflammation, product buildup, and oily scalps that feel tight or itchy by day three.
Evidence
Well established for dandruff; salicylic acid scalp scrubs are less studied but mechanistically sound.
Good to know
Use once or twice a week, not daily — over-exfoliating the scalp causes the same irritation it is meant to fix.

Protein and moisture balance (hydrolysed keratin, glycerin, fatty alcohols)

Hair with too little protein feels mushy and stretches before breaking; hair with too little moisture feels stiff and snaps. Protein treatments temporarily patch gaps in the cuticle, while humectants and emollients restore flexibility.

Best for
Curly, coily, colour-treated or heat-styled hair that alternates between feeling gummy and feeling brittle.
Evidence
Well established in cosmetic science, though the right ratio is individual and found mostly by trial and error.
Good to know
If hair snaps when stretched dry, it usually needs moisture, not more protein. Over-proteinising makes hair feel like straw within a wash or two.
Step-by-step guide

How to build a hair and scalp routine, step by step

Hair problems fall into three buckets — the follicle (is it growing), the shaft (is it breaking), and the scalp (is it inflamed or flaking) — and they need different fixes. Work through these steps to figure out which bucket you're in before spending on treatments. Aura does this from your intake and names specific, budget-matched products.

  1. 1. Work out whether you're losing hair or breaking hair

    Pattern hair loss thins the crown or hairline gradually and the shed hairs usually have a tiny white bulb at the root. Breakage shows up as short, frayed pieces of uneven length, often worst a few inches from the scalp near the last colour or heat service. The treatments for each barely overlap, so this diagnosis step changes everything downstream.

    • Do a gentle pull test: more than 4–5 hairs coming away per pull, repeated over days, points to shedding
    • Check for tiny broken stubs along the hairline or crown, a common early sign of pattern loss
    • A dermatologist can confirm with a scalp exam if the picture is unclear
  2. 2. Address scalp inflammation before anything else

    An inflamed, flaking or itchy scalp undermines any growth or strengthening treatment layered on top of it, and can itself accelerate shedding. Calm it first with an antifungal or exfoliating shampoo, then reintroduce other products one at a time.

    • Use a ketoconazole or zinc pyrithione shampoo 2–3 times weekly until symptoms settle
    • Avoid stacking multiple active scalp treatments at once while diagnosing
    • Persistent, painful or spreading flaking needs a dermatologist, not more products
  3. 3. If it's pattern loss, start the evidence-backed treatments and commit to a timeline

    Minoxidil is the reasonable first step for most people and doesn't require a prescription. Finasteride is a meaningful step up in effectiveness for many men but is a prescription medicine that needs a real conversation with a licensed provider about risks, not a routine to start unsupervised.

    • Photograph the same angle under the same light monthly — memory alone won't catch slow change
    • Give minoxidil a full 4–6 months before judging it; hair cycles are slow
    • Raise finasteride, and any other prescription option, with a doctor rather than sourcing it informally
  4. 4. If it's breakage, fix the routine before adding products

    Heat styling, tight elastics, harsh brushing on wet hair and over-washing are the most common causes of breakage, and no serum fixes a habit. Reduce the mechanical and thermal stress first, then layer in bond-builders or protein treatments to repair existing damage.

    • Apply a heat protectant and keep tools under 180°C (365°F) where possible
    • Detangle wet hair with a wide-tooth comb from the ends up, never a brush from the root down
    • Space out bleach and chemical services; damage is cumulative and slow to reverse
  5. 5. Match wash frequency and moisture to your texture, not a generic rule

    Straight, fine hair gets oily fastest and often needs washing every 1–2 days; coily and curly hair produces the same oil but it travels slowly down the shaft, so washing every 4–7 days keeps natural oils where they're needed. Forcing one texture's schedule onto another texture causes the exact problems people are trying to fix.

    • Fine, straight hair: wash more often, condition mid-lengths only
    • Curly, coily hair: wash less often, condition generously root to tip
    • Use co-washing or scalp-only shampooing between full washes if oil control and dryness fight each other
  6. 6. Reassess at 12 weeks, not 2

    Hair grows in a slow, staggered cycle, so almost nothing in this category shows a real result inside a month. Give any single change 8–12 weeks before adding or swapping the next thing, and change one variable at a time so you know what actually worked.

    • Keep a simple log of what changed and when
    • Resist changing three products at once after a bad week — it hides what worked
    • Escalate to a dermatologist if there's no change at all by 4–6 months

Questions

What is the best shampoo for thinning hair?
The best shampoo for thinning hair is one that focuses on scalp health and volumizing effects rather than claiming to regrow hair on its own. While ingredients like ketoconazole, caffeine, and saw palmetto are common in these formulas, they are typically contact-only and don't stay on the scalp long enough to mimic the effects of a dedicated leave-in treatment. Look for lightweight, sulfate-free cleansers that remove excess sebum without stripping the hair, as a congested follicle can hinder healthy growth. The goal of a thinning-hair shampoo is to create the optimal environment for your existing hair to appear fuller while keeping the scalp clear for more targeted growth interventions.
Does rosemary oil for hair growth actually work?
Rosemary oil is a popular natural alternative for hair growth, though the scientific evidence supporting its efficacy is still preliminary compared to standard treatments. One widely cited study suggested that rosemary oil was as effective as 2% minoxidil after six months of use, but these results haven't been widely replicated in large-scale clinical trials. If you choose to use it, ensure it is properly diluted in a carrier oil like jojoba or almond oil to avoid scalp irritation. It is best used as a scalp massage treatment a few times a week. However, if you are experiencing significant hair loss, it shouldn't replace evidence-based medical treatments without a discussion with a specialist.
How do I build a sustainable hair care routine?
A sustainable hair care routine is built on three pillars: cleansing for your scalp type, conditioning for your hair length, and protecting the cuticle from heat and environmental damage. Start by identifying your scalp's oil production—oily scalps need more frequent cleansing, while dry scalps benefit from moisture-rich formulas. Always apply conditioner only from the mid-lengths to the ends to avoid weighing down the roots. Finally, incorporate a heat protectant if you use tools and a leave-in treatment for hydration if your hair is porous or curly. Consistency matters more than complexity; a simple three-step process that you actually follow will yield better results than a ten-step routine you skip.
How often should you wash your hair for optimal health?
How often you should wash your hair depends entirely on your scalp's oil production and your hair's texture. Those with fine hair or an oily scalp may need to wash daily or every other day to prevent sebum buildup and flat hair. Conversely, individuals with curly, coily, or very thick hair often find that washing once or twice a week is sufficient to maintain moisture without stripping natural oils. Washing too frequently can lead to a dry, itchy scalp, while washing too rarely can cause scalp inflammation or dandruff. Listen to your scalp: if it feels itchy or looks oily, it is time to cleanse.
What are the red flags for hair loss that require a doctor visit?
You should see a doctor if you experience sudden, patchy hair loss, scalp pain, or if you notice hair falling out in large clumps. While gradual thinning can be a normal part of aging or genetics, rapid changes often signal an underlying issue like a nutritional deficiency, hormonal imbalance, or an autoimmune condition such as alopecia areata. Other red flags include significant itching, burning, or visible scarring on the scalp where hair has been lost. A dermatologist can perform a scalp biopsy or order blood tests to determine the cause. Early intervention is often critical for reversing or slowing down many types of non-genetic hair loss.
How do you start a hair care routine as a beginner?
Start with three things: a shampoo matched to your scalp (gentle or clarifying for oily scalps, moisturizing for dry ones), a conditioner on the lengths only, and a wash frequency your scalp tolerates without itching or greasiness. Run that for four weeks before adding anything. Then add one targeted step for your main goal — a leave-in or weekly mask for dryness and breakage, a scalp treatment for flaking or thinning. Hair and scalp change slowly, so adding several products at once makes it impossible to tell what is working.
What is the correct order of hair care products?
Shampoo first to clean the scalp, then conditioner on the mid-lengths and ends, rinsed out. A mask replaces conditioner once or twice a week. On damp hair, apply leave-in conditioner first, then styling products (cream, gel or mousse), and heat protectant last before any hot tool. Oils go on at the very end in a small amount to seal ends — or before washing as a pre-shampoo treatment. Scalp serums go directly on the scalp, usually on clean, dry or towel-dried hair.
How do you build a hair routine for curly or dry hair?
Curly and dry hair need moisture held in, not stripped out. Wash less often (one to three times a week) with a sulfate-free or low-lather shampoo, use a rich conditioner every wash, and apply a leave-in to soaking-wet hair. Seal with a cream or gel while hair is still wet to hold curl shape, and let it air dry or diffuse on low heat. Add a deep-conditioning mask weekly. Satin pillowcases or bonnets reduce overnight friction and breakage more than most extra products do.
How long does a new hair routine take to show results?
Feel and manageability can change in one or two washes. Less breakage and frizz usually show in four to eight weeks. Scalp changes — less flaking or oil — take about a month of consistent use. Visible regrowth from thinning treatments takes three to six months because hair grows roughly half an inch a month. Take photos in the same light every month; day-to-day comparisons are unreliable.
