What It Is

Biotech-powered mini routine repairs damage, protects from heat, and smooths all hair types—featuring molecular designs by Artist Jen Stark. 

What It Does

Repair damage: K18PEPTIDE™ reverses damage from lightener + color, chemical services, and heat in just 4 minutes*.

Deeper heat protection than ever before*: resilicore™ heat-shielding technology goes into hair's inner cortex where heat damage can occur, forming a protective shield BS5that fortifies from within.

Fight frizz from within: K18PEPTIDE™ works to address deeper-level damage that causes frizz—repairing and strengthening damage at the innermost layer of hair to reverse damage that leads to frizz.

What Else You Need to Know

Kit includes: 
1 - leave-in molecular repair hair mask 0.5oz 
1 - molecular repair hair oil 0.34oz

Rated 5 out of 5 by from Love this product A little goes a long way. Do not use too much or your hair will feel gummy. I can use this on its own without styling products and my hair is amazing.

Rated 5 out of 5 by from Great K18 product! I really loved this K18 HeatBounce Conditioning Heat Protectant. My hair felt really soft and manageable even after blow-dry and iron curling. I also noticed that my hair much less damaged unlike with other products. I highly recommend it!

Rated 5 out of 5 by from Only need a small amount I have definitely overused this before when my hair was wet and it got greasy much earlier than I would’ve liked. I only need a few drops for all my hair but I do have fine hair. It works great and isn’t too heavy as long as you use a little.

Rated 5 out of 5 by from Fantastic The most dependable heat protectant I have come across. After trying many heat protectants, this one passes all the tests for me. Can be used on wet, or dry hair without any added weight to the style. This outperforms any of the other heat protectants I have used. Just wish it came in a larger bottle!
