Little bottles mean business

Gemma Boosters are the brainchild of one of our amazing scientists. Combined with Gemma Shampoos and Conditioners, they help address key frustrations like dry hair from chemical treatments or frizz from humidity.

Easy squeezy

When you get your shipment, just squeeze the entire booster bottle into the shampoo or conditioner (read the booster label to find out which one). Then shake. And voila--your product is ready to go!

Sort of like fairy dust,
but sort of not

Our boosters are designed to be compatible with Gemma products. So ONLY add them to Gemma Shampoos and Conditioners. We can't promise they will work with other hair products. Or do your taxes. Or walk your dog.
