Henna & bleach!!

[ClaireJones]

Hi guys, I had a lady I went to couple of weeks ago for a restyle. She has blue highlights, where her last hairdresser put bleach over her henna dyed hair. Never come across this before would the blue come out with colour correction or would it react again ? X

It will keep reacting. Never do any chemical service over hair that has EVER been henna'd. The henna treated hair must grow out.

Thankyou, I thought it would just keep reacting. It's good to come across this in hairdressing as I've never seen what happens after a service has been done on henna. X
