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.

"First time trying this and so far so good. Clean, fresh rosemary scent that isn't overwhelming (i usually need unscented). Hair is soft. I wouldn't say I see much shine, but I do have a lot of color treated grays so that might be asking too much for a shampoo. I will try the conditioner next."
— Jessica L. (5/5)
"cleans hair well and smells amazing. love the bottle design. can be a little drying so i don’t use it every time i shampoo"
— ainsley d. (5/5)
"Absolutely love this shampoo, it makes my hair so silky and smells incredible"
— Devon R. (5/5)
"My hair loves this shampoo and I love the smell."
— Amy G. (5/5)
"I was using another all natural brand that cleaned my scalp really well, almost too well. Like it left my hair feeling kinda dry. This cleans well and leaves my hair silky soft. I was worried the rosemary was going to be powerful but you barely smell it all. It smells really nice, tingles a little bit too. It’s too early to know if it helps with hair growth but so far my hair feels stronger. I’ve been dealing with alopecia for years so I’m very cautious about the things I use in my hair. This is been fine so far, I will definitely buy it again."
— Lorraine L. (4/5)
"This shampoo and conditioner feels so great. It fully rinses out. Doesn’t feel detergenty and stick in your hair. Kept my hair clean for about 4 days, and I work out everyday."
— Suzie R. (5/5)
"Leaves my hair so soft and free of any residue. Definitely a new part of my shampoo routine that's here to stay!"
— Sarah B. (5/5)
