What's actually happening to your hair.
Most thinning is hereditary and gradual, driven by how your follicles respond to a hormone called DHT. Understanding your type of loss is the first step, because the right treatment depends on what is actually causing it.
Androgenetic alopecia
The most common cause of thinning in both men and women. It is hereditary and progressive, which is why acting early matters more than waiting to see how far it goes.
DHT and miniaturization
In sensitive follicles, the hormone DHT gradually shrinks the hair shaft over each cycle. Strands grow finer and shorter until the follicle stops producing visible hair.
Shedding vs. loss
Everyone sheds 50 to 100 hairs a day. Pattern loss is different: a receding hairline, a widening part, or diffuse thinning that does not bounce back.
Earlier works better
Treatment protects the follicles you still have. Once a follicle is fully dormant, it is much harder to revive, so the best results come from starting sooner.
Men's pattern
Usually a receding hairline and thinning at the crown, driven largely by DHT sensitivity. Often responds well to DHT-lowering medication plus minoxidil.
Women's pattern
More often diffuse thinning across the top with a widening part. A clinician chooses options appropriate for women and screens for other causes first.
A licensed clinician reviews your photos, pattern, and history to confirm what's behind your thinning before recommending treatment. If something else is the cause, they'll tell you and help you find the right path.

Protect the follicle, then rebuild.
Lower DHT at the root
Medications like finasteride reduce the DHT that miniaturizes sensitive follicles. Less DHT means less of the signal driving hereditary loss, so the hair you have is protected.
Reawaken the follicle
Minoxidil supports blood flow to the follicle and extends the active growth phase, which can thicken existing strands and encourage dormant follicles back into a healthier cycle. It comes as a topical solution or foam or, in select cases, as a low-dose oral tablet prescribed off-label.
Support the scalp
A healthy scalp grows healthier hair. Ketoconazole 2% shampoo can calm inflammation and create a better environment for growth. Your provider decides whether to add it based on your case.
Medications a provider may consider for you.
Finasteride
Lowers DHT, the hormone most linked to hereditary follicle shrinkage. An FDA-approved option for men's pattern loss.
Minoxidil
Supports follicle blood flow and extends the active growth phase to thicken and maintain hair.
Dutasteride
Stronger DHT reduction for select cases when a clinician determines it is appropriate. Prescribed off-label.
Spironolactone
An option for women's pattern thinning that addresses hormone-driven loss. Prescribed off-label. Not for use in pregnancy.
Ketoconazole 2% shampoo
Calms the scalp and supports a healthier environment for growth alongside core treatment.
Which medications are appropriate, and at what dose, is a clinical decision your provider makes from your pattern and history. Dutasteride, oral minoxidil, and spironolactone are prescribed off-label. A prescription is required. Individual results vary.
Why people choose KAYU for their hair.
A real clinician, on video
You speak face to face with a licensed clinician who reviews your photos, pattern, and history before anything is prescribed. Not a chatbot, not a one-way form.
Chosen for your pattern
Your provider chooses FDA-approved medications for your type of loss, including the dose and format, rather than handing everyone the same kit.
Men and women
Hereditary thinning looks different across people. KAYU clinicians treat both, and choose options that are appropriate for you.
Honest about side effects
Your provider reviews the real trade-offs of each medication, including possible sexual side effects with finasteride, so you can decide with clear information.
Transparent pricing
You pay for care. If a treatment is prescribed, the pharmacy bills your medication separately at cost, with no KAYU markup.
We say no when it's right
If your thinning points to another cause, a clinician tells you and helps you find the right path instead of selling you a prescription.
A realistic timeline.
Some people see a temporary increase in shedding as the hair cycle resets. This is expected and usually settles. Keep going and message your care team with questions.
Most people start to notice the first real changes: less shedding, and finer hairs beginning to look fuller. Consistency every day is what makes the difference.
Fuller results build over time with continued use. Treatment maintains its benefit only while you keep using it, so your provider helps you find a routine you can stick with.
Timelines are general and not a promise of results. Individual results vary, and your provider monitors your progress and adjusts your treatment along the way.
Your plan, built by real clinicians.
Hair loss is medical, so your plan is built and reviewed by a licensed clinician, not a kit picker. Named, credentialed, and accountable for your results.

Hair loss treatment FAQ.
Does hair loss treatment actually work?
The medications KAYU clinicians prescribe are FDA-approved or commonly prescribed off-label for hereditary hair loss. They work best when started early and used consistently. They help protect the hair you have and support new growth, but no treatment works for everyone, which is why a licensed clinician reviews whether it's appropriate for you first. Individual results vary.
How long until I see results?
Hair grows slowly, so patience matters. Most people notice changes around 3 to 6 months of consistent daily use, with fuller results building after that. Some people see an early, temporary increase in shedding before improvement, which is expected as the hair cycle resets.
What's the difference between hair restoration medications?
They work in different ways and may be prescribed separately or alongside each other. Finasteride lowers DHT, the hormone that shrinks sensitive follicles, so it slows the underlying cause of hereditary loss. Minoxidil supports blood flow to the follicle and extends the growth phase, which helps thicken and maintain hair. A clinician decides which, or both, fits your pattern.
What are the side effects of DHT-blocking hair medication?
Finasteride can cause sexual side effects such as reduced libido or erectile changes in some people. Your provider reviews the full picture with you before prescribing, and you can choose topical minoxidil alone or a different approach. Tell your provider about any side effects you notice.
Can women use KAYU for hair loss?
Yes. KAYU clinicians review women's thinning and offer appropriate options. Important safety note: finasteride, dutasteride, and spironolactone must not be used during pregnancy, and women who are or may become pregnant should not handle finasteride or dutasteride. If you are pregnant, may become pregnant, or are breastfeeding, your provider will choose an appropriate path or recommend waiting.
Topical or oral, which is better?
It depends on your pattern, your preferences, and how you tolerate each. Oral medications are simple and consistent. Topicals act at the scalp and can reduce systemic exposure for some people. A licensed clinician recommends the format that fits you, and each medication is prescribed individually.
Do I have to stay on it forever?
Treatment maintains its benefit only while you use it. If you stop, the hair you protected will gradually resume its natural pattern over the following months. Many people stay on a maintenance routine long term, and your provider helps you find something sustainable.
How does billing work, and do you take insurance or HSA / FSA?
You pay for your provider review and care. If a treatment is prescribed, the pharmacy bills your medication separately, at cost, with no KAYU markup. No insurance is required, and many patients use HSA or FSA funds toward eligible care. You're only charged for medication after a licensed clinician approves it.
What about side effects, and can I cancel anytime?
A licensed clinician reviews your health history before anything is prescribed, and declines or adjusts treatment if it isn't appropriate for you. Like any medication, hair loss treatments can have side effects your provider reviews with you. There's no long-term commitment, and you can cancel anytime.
