What is an undertone?

An undertone is the color beneath the surface of your skin, which never changes (even with a tan). There are three types of undertones:

Pink/Cool

I see red or pink undertones around the perimeter of my face and neck.
My skin burns easily, but barely tans.
My skin looks better in silver jewelry than gold.

Neutral

I see both pink and yellow undertones around the perimeter of my face and neck.
My skin sometimes burns and sometimes tans.
My skin looks good in both gold and silver jewelry.

Yellow/Warm

I see yellow or golden undertones around the perimeter of my face and neck.
My skin rarely burns, but tans easily.
My skin looks better in gold jewelry than silver.

Reviews

Skip this one (especially if you have thick curls)

"Extremely mediocre for thick curls. Not even half as good as my usual Acure moisture conditioner which is a fraction of the price. The one from Innersence is much better too, though also on the pricey side. I also really dislike the fragrance so much that I almost threw out the bottle after the first use. Smells like generic cheap perfume."

Didn’t work for my hair

"Wanted to like it but I don’t think it worked for my hair type."

Laura C. (3/5)

Finally an anti frizz product that works!

"This leave in mask is absolutely the best I’ve ever used on my hair!!! I have been trying anti frizz products for years and years and having curly/wavy and a lot of fine hair, it has made it impossible until now. Thank you necessaire! Not only does it work when first used, it last and helps for days leaving my hair healthier and frizz free!!! My hair is mostly grey so this is a fantastic product that works!"
