How long should I trial a hair treatment before asking for a review?

Hair grows in cycles, so a short trial may not show whether a treatment is helping. Many scalp treatments are assessed over several months, sometimes six months or longer. Results vary. The right review point depends on your diagnosis, medication, and how consistently you use it.

Ask your physician when to check in and what changes to watch for. Scalp treatments and lash treatments may have different review schedules. Do not use the timing for one product to judge another product.

Photos taken in similar lighting, with the same hairstyle and camera angle, can help track changes. Your physician may look at shedding, hair density, and scalp health rather than relying on one photo or one day's hair fall.

Some people notice early shedding with minoxidil, but new shedding should not automatically be dismissed. Contact your physician if it is heavy, ongoing, or accompanied by pain or irritation. Do not increase the dose to try to speed up growth. Results vary.
