Pro Longer mask for long hair helps thicken the appearance of long hair for visibly healthier and stronger looking lengths.
The Filler A-100 technology used is patented to L'Oréal Professionnel, and it works by penetrating the fiber core to plump and thicken the hair from the inside. Amino acids in the formula work to strengthen the hair from the outside. The formula works on thin ends, or areas where help is most needed.

​*instrumental test shampoo + lotion + mask

After Pro Longer shampoo, apply to towel-dried hair.
Leave in 3 to 5 minutes.
Rinse thoroughly.

It’s very good for my hair

I have been using the mask for 2 months now. My hair is much better. I have fine, bleached hair.

Heavy on my hair!

I have thin, fine hair and have had this treatment a few times. It leaves my hair heavy without much lift and volume! I am sensitive to scents and this product leaves a scent in my hair until I wash it! I have used a better product in the past and I am not a fan of this product! I love the Claypac much better!
