We lose on average 50-100 hairs from our head on a daily basis. As new hair grows through the follicle, old hair eventually falls out as part of the ‘exogen’ phase of hair growth. However, when this process is imbalanced, with less hair growing than falling out, it can make the hair feel thin, flat and lacklustre.

Each Hair Growth & Volume Duo contains a full size;

Caffeine Stimulating Scalp Treatment (150ml) : An overnight scalp treatment that uses caffeine powder and an ingredient called Redensyl™ to help reduce hair loss by stimulating the scalp and hair follicles, therefore encouraging hair growth and helping to improve hair thickness.

Peptide Volumizing Hair Treatment (100ml) : When hair sheds it can feel thin and lacklustre. Using Peptides, the chains of amino acids that support proteins naturally found in hair, our unique lightweight formula increases hair thickness and volume.
