Hi, I want to have the 12 week blow dry/brazilian blow dry done but I have Hair Extensions in. Does anyone know if this is ok to do?

If anyone has already had it done or has done it on Hair Extensions does it make a big difference to the hair? My extension hair has gone quite dry and frizzy in the last couple of weeks

Depends on the application method. If they have been applied using resin, the protein in the brazillian blow dry would degrade the bonds. Other methods may be ok, but its best to check with your extensionist first.

With Kerastraight the company line is you can apply extensions after the first shampoo.

Hope this helps
