Searching for keratin? · for men

Men's keratin. Here's what you're actually buying.

"Keratin" isn't a treatment. It's a word salons put on a menu. In my chair the smoothing men ask for is Straightment Demi, or Straightment Permanent when the curl is strong, and I choose which.

Frizz, sorted

  • Humidity: you leave the house dry and arrive looking like you walked through a car wash.
  • Gym and sweat: it frizzes after every session, and the crown stands up.
  • Travel: hard water, hotel shampoo, a different climate every week. It is done in London and works wherever you land.
  • Grey coming in: grey hair is often wirier and frizzier than the hair it replaced.

What it won't do

It won't make you look ironed. On men I stop short on purpose: shiny, flat, uniform hair is the failure mode. It won't fix a bad haircut either; sometimes the answer is a different cut, and I'll say so.

Is keratin safe?

It depends on what is in the bottle and who is holding the iron. Formaldehyde is banned as an ingredient in UK cosmetics; ingredients that release it must be labelled. I tell you what goes on your hair before it goes on. The full answer is in the guide below.

Why men book this with me

Most of London sells keratin to men with "Men –" stuck on the front of a women's service. Same bottle, same finish, polished and flat. I've been straighteningDOWN since 1999 and I finish men's hair so it reads as your hair on a good day.

Questions men ask

Is it actually keratin?

"Keratin" is a word on a menu. With me it's Straightment Demi, or Permanent when the curl is strong.

Is it safe?

It depends on what's in the bottle and who holds the iron. I tell you what goes on your hair before it goes on.

How long does it last on short hair?

Around two to three months, because you cut it off. No line.

Will it make my hair look ironed?

No. On men I stop short on purpose.
