Expert Biotin Restoring & Restructuring Hair Mask-in-Serum

This revolutionary formula works to leave you with thicker, smoother, healthier hair, whilst deep-cleansing and restoring pH levels.

The Science

The Expert Biotin Restoring & Restructuring Hair Mask-in-Serum combines Biotin, Lemon Extract, and Glycolic Acid to help give your hair the transformation you desire. 

Biotin aims to thicken hair and stimulate growth, whilst Lemon Extract works to deeply cleanse the scalp and hair follicles, restore healthy pH levels, and remove build-up of oils and pollutants, resulting in healthier and stronger hair follicles.

Glycolic Acid helps moisturise and exfoliate the scalp, resulting in a healthier look and texture.

A True Beauty Ritual

Getting the most from your Expert Biotin Restoring & Restructuring Hair Mask-in-Serum:

1. After shampooing and conditioning your hair, scrunch the ends of your hair with a towel to remove excess water or let the hair air dry a little. Applying the mask to damp hair will allow it to work best.

2. Apply 2-3 pumps of your mask-in-serum onto your palms and rub them together. The amount applied should depend on your hair’s volume and length. A pea-sized amount is often enough for shorter hair, as too much may oversaturate.

3. Run your hands through your hair. Using your fingers, apply directly on the roots as well as the ends, making sure to distribute the mask throughout the hair as evenly as possible.

4. Leave the hair mask in and dry with a hair dryer.

#AvantTips: Do not use the mask on dry hair. Using a hair dryer to dry your hair will help activate the ingredients in order to restore and rejuvenate.

Store in a cool and dry place.
