Details & care

What it is: A protein-enriched gentle cleanser that melts dirt and buildup to help hair look stronger and more resilient.

Who it's for: Ideal for all hair types.

What it does: Curly hair needs gentle cleansers that don't strip away natural oils, but not all hair types like co-washing. If your hair is fine or greasy, using a co-wash may actually weigh it down and make it look flat. That's when the Core Strength Shampoo comes in. This cleanser will look and foam like a traditional shampoo, but it contains much gentler ingredients that will not dry curls out, so it is suitable for frequent washes and color-safe. It is also enriched with proteins and fortifying actives that will help strengthen the hair and protect it from breakage.

How to use: Wet your hair thoroughly, then dispense a generous blob of product on your palms and apply directly to the scalp. Massage gently but vigorously to clear the scalp and melt down all dirt and product buildup. Rinse thoroughly until water runs clear.

Wonderful

This shampoo product is my go to ever since I found it. It’s the best for when my hair needs a refresh and stripped of all oils. It leaves my hair fresh and feeling clean. The guava smell in this is amazing as well.

Not bad

[This review was collected as part of a promotion.] This is a good, gentle cleanser for your hair, with not too much protein in it. The only reason it doesn't get 5 stars is that it doesn't lather well on day 2 hair. I wash every other day so there shouldn't be much dirt buildup, but it doesn't lather well. If I wash it daily, no issue with the lather. Otherwise, nice product.
