Keratin blow dry question

[GinLover]

Hi Everyone!
Newbie here.
I’ve booked in for a keratin Blow dry Course. My tutor (currently halfway through level 3), said I can’t bring someone in with bleached hair.
However, I’ve been reading loads online and most say that it’s a perfect treatment.
The person I want to bring in has bleached and really coarse, thick hair and would really benefit from the treatment, I think.
Any help would be appreciated.
Sonia.

I think it depends what system you are using.. Nanokeratin & 72 hair allow bleached hair. Some may advise against this. there is so many systems with different chemicals this may be why your tutor is saying no.

Thanks, Charlotte.
I honestly thought my tutor was just being funny - she has a tendency to make the rules up as she goes along.
