Treatment or Repair Conditioners are the more deeply penetrating formulas that are left on the hair from ten to thirty minutes. These conditioning formulas often include ingredients to restore proteins and moisture to the hair. Hair moisturizing masques and protein packs fall in this category.
Moisture-rich versions of these deep treatments are especially good for chemically treated hair because of the full penetration of the moisture agents in the product, as well as ingredients to then smooth the cuticle and seal in moisture that has been added.
The high-protein versions of this product are designed to gently swell the hair, allowing it to pass through the cuticle of the hair shaft and replenish the proteins in the cortex, restoring the strength and elasticity of the hair. Protein packs are especially good for use prior to wet styling to give better, longer lasting results.

Hair treatments and repairs conditioners are best used to treat specific hair issues. If you have severely dry hair, a deep conditioner can restore softness and moisture. If your problem is brittle, weak hair, the a high-protein repair conditioner can strengthen and revitalize the damaged hair. These deep- care treatments should be used no more than once a week, and are great in conjunction with normal everyday conditioners.
