Helen's Take 🧐

I bought this mask several times. It is a great money investment because you only need one pump for the treatment (pea-sized amount). You should rub it between your hands (after washing the hair with shampoo), until your hands become white and only then transfer it to your hair. Allow 4 minutes to penetrate and proceed with your favorite cream/oil.

The mask works over time. You have to use it for 4-5 times. After this period you will see an improvement in your hair's health. Your masks and other hair care products will start working better. If you feel dryness during the time of K18, you can use a conditioner/mask after the 4 minutes of K18 have passed. The brand allows this technique. Or maybe try layering leave-in products (spray-cream-hair oil). The mask really helps to make the hair stronger, reduces breakage, and helps detangle the hair.

If you have colored hair or a lot of breakage this is your product. Just make sure, that after the 4-5 treatment you use a moisturizing mask/conditioner to restore the moisture balance in your hair.
