What Folicerin is

Folicerin is a topical shampoo marketed to reduce hair loss and support growth, built on caffeine, licorice and botanical extracts.

What the ingredients can do

Caffeine has some limited research for topical application to hair follicles, and the formula adds licorice, ginseng, amino acids, biotin and zinc. As a gentle, low risk product it is reasonable enough.

The honest limits

Two things temper it. A shampoo is rinsed off after a couple of minutes, so contact time is short compared with leave on treatments. And the headline figures, like reducing hair loss in 92 percent of users or 8.7 percent more density, are in house numbers, not independent trials. It is not in the same evidence league as minoxidil.

How to use it

Use it like a normal shampoo, leaving it on for two minutes before rinsing, up to five times a week. Patch test if your scalp is sensitive, and note it contains wheat and soy proteins.

Our verdict

A pleasant, low risk supportive shampoo with modest, mostly cosmetic benefits. Reasonable as an add on, but for real hair loss, look at proven treatments and see a doctor.
