FAQ

It’s formulated to treat most hair types. Think of it as beauty sleep for your hair. If you have specific concerns:

  • If damage is your primary concern, use Restore Mask, Instant Protection or Instant Repair to undo the damage. Add Night Cap to help keep your hair looking healthy.
  • If frizz is a major concern, use No Frizz Leave-In Conditioner to help block humidity and fight frizz. Add Night Cap to help keep your hair looking healthy.

 

Night Cap is keratin and straightening treatment safe. Keratin and straightening treatments are damaging to hair. Night Cap is a perfect product for anyone seeking to keep hair looking and feeling great, particularly after having a straightening treatment.

Night Cap is also sodium-chloride free so it will not affect the results of your treatment.

Night Cap lasts through multiple shampoos, including when you use a clarifying shampoo.

In general, we recommend not over-using clarifying cleansers, as they strip hair, adding to the cycle of damage.

We recommend using Night Cap the evening after your color service at a salon.

If you color your hair at home, apply the color according the manufacturer’s directions. Then follow with Night Cap.

No, it is formulated to not affect your color.

We recommend not applying Night Cap over a silicone or oil-based serum because they minimize the ability for Night Cap to soak into your hair. We recommend if you have a lot of styling product in your hair, to brush your hair to help remove any residue before applying Night Cap.

If you wash your hair in the evening, we recommend you apply Night Cap prior to any other stylers or leave-ins to ensure the greatest benefits from Night Cap. You may not find the additional stylers or leave-ins necessary on the nights you apply Night Cap.

The benefits will be the same regardless if you leave it in or rinse/shampoo it out of your hair the next morning. Night Cap’s benefits build over time so do whatever works best for your routine.

You've probably heard a lot about sulfates and generally think they are bad for hair.

You should watch out for sulfates in Shampoos as when they are used in lathering, cleansing products they can strip hair of its natural surface oils making it feel rough, dry and brittle. Sulfates can also strip the scalp of its natural oils, leading to dryness and irritation. Examples of commonly used sulfate ingredients that can be stripping include: Sodium Lauryl Sulfate, Sodium Laureth Sulfate, Ammonium Lauryl Sulfate, Sodium Laureth Sulfate. You should watch out for these in shampoos.

Sulfates do not inflict damage on hair when used in conditioners or treatments. When used in these products they actually help make hair smoother, softer and visibly healthier.

Sulfates in conditioners and treatments do not damage chemical treatments or color. Characterizing them as not good for your hair in these types of products is incorrect.
