From the consumer side.
Ive had the nanokeratin treatment and im sorry to say it didnt work at all.
The hairdresser however had good results on other people.
My hair is kinda puffy but no excessively frizzy.
It was dissapointing as id followed instructions to the letter.
The salon were very good about it and refunded me.
Thanks everyone I think the main problem with brazilians now the formaldehyde has been taken out they no longer straighten the hair much. Great for condition but most clients want a degree of smoothing and straightening and are disappointed with the results.
