Can you use them together to double up on moisture, or should you only use one at a time? In this post, we’ll answer this question, so you’ll know which product to use and when.

Do treatments replace conditioners?
Short answer: There is little reason to use both, however they may be used together.
Most treatments perform the same function as conditioners. A conditioner simply does the regular job of conditioning the hair. It provides the light hydration and manageability you need after every wash. It also leaves behind a thin film to keep your hair moisturized for days. However, treatment gives your hair deeper hydration and more substantial hair repair. There are treatments for every hair problem: damage, thinning, frizz... you name it. 

Treatment or Conditioner: Which should you use first?
Short answer: If you decide to use them together, be careful about the order. 
Conditioners can be safely used every time you wash your hair. However, if you feel like your hair is extra dry and frizzy, or needs extra care, you might want to use treatment before conditioner to remedy those issues. Repairing damage from the inside first using treatment and then coating the outside to finish is the right way to take care of your hair.
