In between treatments, use Keratherapy Keratin Infused Moisture Shampoo and Conditioner to keep strands strong and silky.

Keratherapy

Birchbox Breakdown

Whether it’s coloring, heat styling, or overzealous detangling, we’ve all been guilty of committing girl-on-hair crime. Make amends to your crispy tresses with this lush masque from Keratherapy, which repairs, rehydrates, and rebuilds even the most desiccated hair. The great-smelling formula rinses out to leave strands glossy, frizz-free, and strong enough to withstand another harrowing round with your curling iron.

How it Works

This rich conditioning mask contains a unique blend of omega fatty acids and vitamins that smooth and moisturize damaged hair. Kerabond Technology® delivers keratin deep into the hair shaft, strengthening from within while simultaneously sealing the cuticle layer.

How to Use

After shampooing, apply generously to damp hair from root to ends. Leave in for 10-15 minutes and rinse well with cool water. Style as usual. Use once or twice a week for optimal results.

Phenomenal for Long, Tangled, Dry Hair
Sampled

This masque was a savior to my hair. My hair is waist length and thick so it is very dry and has horrible damage but with only one use of this masque, my hair feels AMAZING. I highly recommend this to anyone with brittle hair and a dry scalp. I also color my hair which causes awful tangles that with one simple application of this product, completely vanished. You will thank yourself when you feel your soft, untangled hair and smell how great the scent of the masque is.

I bought this in conjunction with the shampoo and conditioner. Using it once a week leaves my hair feeling moisturized, soft and manageable.

The best!
Purchased

I love, love, love this product. It smells amazing and makes my hair so soft! I treat it more as a weekly mask treatment instead of daily use.

Soft Hair
Purchased

This product make my hair very soft and lux feeling after I use it. The only downside I can see is that the smell, while pleasant, could be considered overpowering to those who have a sensitivity to smells.

dramatic change

I received a sample of Keratherapy Conditioning Masque in my birchbox a few months back. When I tried the sample out I knew I had to buy the bottle. I have really thick, long, and frizzy hair. This masque changed the appearance of my hair. I was about to put the mask in before a big night out. I let it in a little bit and washed it out. My hair hardly needed to be straightened. And not to mention the smell. I am really picky with smells, but this blew me away. By far the best masque I have come in connect with in a long time. Highly recommended.

It actually works!

I have very dry and kinky hair. I've never found a product that works so well! I am actually wearing my hair down more often because it looks so healthy!

Worked for my curly hair. Bounce and shine.
Purchased

Great product for my thick curly hair. Usually my hair gets frizzy by the second day of washing and this product helped my curls maintain their shape even after 3 days. Very satisfied with the results.

Feels great...SMELLS STRONG

It didn't matter how it left my hair, the smell was so strong I was nauseous by the end of the day. I just couldn't handle it. Maybe I didn't get it completely washed out? Pretty sure I did....Just couldn't do it.
