Does this contain formaldehyde?

Yes, but most likely an insignificant amount. That’s what makes it effective, I’ve tried tons of formaldehyde-free version and it’s honestly a waste of time.

How much do I need for one treatment? I have thick short hair

My bottle usually lasts for about 6 treatments and I have long hair

Can anyone advise if this will damage my hair

It didn’t damage my hair, it actually felt the healthiest I’ve known it for years. I have brown wavy hair. It removed the waves completely and lasted longer than expected amount of time. I’ve used it several time now.

How long after treatment can I colour my hair

I only use temporary colours in my hair ,waited about l week
