KerBrian Brazilian Keratin Treatment - for Hair

After applying PURC KerBrian Keratin, wait 3 days before washing your hair with Keratin Daily Shampoo and Conditioner. Make sure not to use shampoo containing sodium chloride to prolong the effects of the treatment.

To use KerBrian PURC Keratin, start by drying your hair 100%. Wash it with Keratin Purifying Shampoo. Apply the keratin strand by strand, leave it on, then use a flat iron at 450°F to seal the treatment.

If you are of Asian or European origin, opt for keratin without formalin. For the Middle East, choose between 5% and 8% formalin. For South America, opt for 5% or 8% formalin. For Africa, opt for 8% or 12% formalin.

The choice of the percentage of formaldehyde depends on the nature of your hair. For naturally curly hair, it is recommended to choose between 8% and 12% formaldehyde. For golden hair, avoid keratin without formaldehyde so as not to change the color of the hair to orange.
