Does caffeine actually help hair growth?

What caffeine does at the scalp

Applied topically, caffeine increases blood circulation at the scalp, which brings more oxygen and nutrients to the follicle. It also appears to counteract some of the effects of DHT, the hormone most associated with pattern hair loss.

That is the reason it appears in our Iminent Shampoo and Conditioner rather than as a marketing word on the front of the bottle.

What it will not do

It will not regrow hair from a follicle that has already closed, and it will not work in a fortnight. Hair grows roughly a centimetre a month, so any honest assessment of a topical product takes months, not weeks.

It also will not counteract the mechanical damage from tight styling. If tension is the cause, no shampoo will fix it.

Getting the most out of it

Massage the shampoo into the scalp rather than the lengths, and give it thirty seconds to sit there before rinsing. Follow with the conditioner on the mid-lengths and ends.

Pair it with the Iminent oil as a weekly scalp treatment. The oil does the nourishing; the caffeine does the stimulating.
