Instructions for Applying Brazilian Keratin Treatment

Brazilian keratin treatment is a specific type of hair treatment that uses chemicals to straighten curly hair. The treatment uses various chemicals and acids, making it an intense procedure that requires specific application instructions and then treatment after you have applied the product.

Application of Brazilian Keratin

According to, which is a manufacturer of Brazilian keratin treatment, there are important steps to applying the straightening product. First and foremost, you must be in an open, well-ventilated facility. Application produces toxic fumes that you want to adequately disperse. Make sure to wash the hair thoroughly to prevent any chemical interactions between the straightener and other hair care products. Dry the hair up to about 80 percent, combing while you dry. Wear rubber gloves for the application.

The key to application is separating the hair into four sections, and applying the keratin treatment to the hair about ½ inch from the scalp. Comb the product through the hair, ensuring that you are not soaking the hair with the product. Allow the keratin to sit in the hair for about 15 minutes, and then slowly dry the hair with a dryer. Finally, divide the hair into 2-inch sections and use a flattening iron to further straighten the hair. Leave the hair alone for about an hour. After an hour, rinse the hair and apply a neutralizing conditioner by massaging it into the hair. Rinse the hair thoroughly after five minutes of allowing the conditioner to work into the hair.

Treatment After Application

Once you have completed application of Brazilian keratin treatment, wear your hair down as often as possible to prevent premature curling. Use a blow dryer and flatiron frequently, especially if your hair gets wet within the requisite three-day waiting period. During the waiting period, you cannot wash your hair, but after you resume hair washing, do not use a sodium-chloride-based shampoo.

What to Avoid

Avoid wearing your hair in a ponytail or using hair ties. Such usage will only cause additional curling in your hair. Always avoid braiding for the same reason. If possible, avoid excessive sweating; moisture causes the hair to curl. Finally, do not use the Brazilian keratin treatment if you are pregnant or if you have allergies to the product, which can cause redness and swelling on your scalp.
