K18 Leave-In Molecular Repair Mask 50ml 

A leave-in treatment mask that works on the molecular level to reverse hair damage in just 4 minutes. The K18PEPTIDE™  is clinically proven to repair damage from bleach + color, chemical services and heat* – with immediate and lasting results to restore strength, softness, smoothness and bounce to hair.

More To Know:

Takes damage repair further – reconnects both polypeptide chains (and as a result, also reconnects disulfide bonds) for strength along the length + width of the hair - offering comprehensive, lasting damage repair

Restores hair from even extreme damage - by working at the innermost layer of the hair, core strength and elasticity are renewed for strong, smooth, bouncy hair

Delivers immediate and lasting results – hair is repaired from the first use and lasts past your next wash, for ongoing reparative benefits

Simplified repair - convenient, leave-in formula works in just 4 minutes, with no extra rinse required

Works on all hair types – because K18PEPTIDE™ works on a molecular level (where all hair is the same), this product is effective on all hair types

Key Benefits:

K18PEPTIDE™  is a biotech-developed peptide that mimics hair's structure to reverse damage by reconnecting polypeptide chains and disulfide bonds broken during bleaching, color and chemical services + heat*.

pH-optimized (5.0-6.0) to help minimize cuticle swelling + put hair proteins in their most resilient state

Cream format enables easy, lightweight application across all hair types, with detangling and softening benefits

Vegan, color-safe, cruelty-free

Best hand cream for extreme rough hands
Size: 16 Fl Oz (Pack of 1)
My husband struggles with really rough hands and it's the best thing we've found. It does have a bit of a medicinal smell, but well worth it for the relief! Highly recommend.

Smells like a disinfectant
Size: 16 Fl Oz (Pack of 1)
I’ve been struggling with eczema terribly this winter, scratching to the point of bruising. Nothing seems to help so I figured I’d give this a try. I will say that it does provide instant relief, but it is short lived and not worth the scent. It smells terrible and reminds me of old fashion Pine Sol. I think there are better products out there. I wouldn’t buy this again.
