It's generally not recommended to use clarifying shampoo frequently after a Brazilian Blowout. Clarifying shampoos can strip the hair of the keratin and shorten the lifespan of the treatment.

Using clarifying shampoo with a keratin treatment will likely reduce its effectiveness. The harsh cleansers in clarifying shampoos can break down the keratin bonds, causing the treatment to fade faster.

Several factors can ruin a Brazilian Blowout, including washing hair too frequently, using shampoos containing sulfates or sodium chloride, and excessive heat styling. Swimming in chlorinated water and using styling products with alcohol can also shorten the treatment's lifespan.

Clarifying shampoo should be avoided if you have color-treated hair, as it can fade the color quickly. It's also best to avoid it if you have very dry or damaged hair, as it can further strip moisture and lead to breakage.
