JanMarc Professional Black Diamond Mask

A treatment specially formulated for dry and sensitized hair, including hair affected by salt and chlorine. It repairs the hair from within, providing deep hydration while strengthening and stimulating hair growth. It also enhances shine, softness, and luminosity.

Directions for use:

After shampooing, apply the mask and massage through the hair. Leave on for at least 5 minutes.

For a deeper treatment, mix with a few drops of Liquid Diamond Hair Oil, apply from mid-lengths to ends, cover with a cap, and leave on for 20 minutes. Optionally, use heat with a thermal cap or hair dryer.

Rinse thoroughly with plenty of water.
