Brazilian Tech Keratin Deep Penetrating Conditioning Treatment by One ‘n Only is formulated to keep hair smooth, shiny, and nourished. This high-performance professional line helps restore hair’s natural keratin that may be lost or damaged during routine styling and chemical or color treatments.

Brazilian Tech Deep Penetrating Conditioning Treatment protects hair against heat during thermal styling and keeps hair smooth and shiny. Natural keratin protects hair from structural damage, strengthens and revitalizes damaged, stressed hair. Keratin is the primary protein of the hair. Damage to proteins within the cuticle cortex of the hair fiber is caused by external factors-UV light, environmental radicals, chemical services and styling.

Brazilian Tech Deep Penetrating Conditioning Treatment helps prevent and protect against associated damage by restored the proteins necessary for healthy looking hair. Brazilian Tech Keratin Smoothing Treatment is a deep-penentrating treament that helps improve hair strength.

HOW TO USE: Apply to clean damp hair. Massage in thoroughly. Leave in 2 – 3 minutes.

Recommended for weekly or bi-weekly use. Ideal as a maintainence regimen following a chemical or color service.


I think this is a good product. My hair was VERY soft and shiny after just the first use. After the second and third use, my hair had some bounce. Whether or not this product is budget-friendly solely depends on where you purchase it. I’ve seen it offered for $6.99 and some stores sell it for $10.99 (which is too much IMO). Rusk has a version of this product and both versions essentially contain the same ingredients. (Rusk Pro Elements Keratin Smoothing Treatment)

Whether or not the concentration of each ingredient is higher or more beneficial in the Rusk version is a mystery to me but you can’t go wrong with either.
