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.

    Caffeine treatment works for me

    They used to sell just the caffeine treatment. I don’t care for the peptide product. Please allow customers to continue purchasing the caffeine product separately. I’ve done the full PRP treatment and used fancy scalp serums … all a waste of money. This caffeine treatment is the only product where I’ve quickly noticed hair shedding (from the root) slow down.

    Its okay.

    Not alot of growth happening and ended up with contact dermatitis patches from the caffeine solution. But the volumising serum makes some difference to my hair. Currently in medical menopause so trying to reduce the hair thinning as much as possible.

    Caffeine is eh

    Volume is nice though.
