Our easy to use spray is designed to add instant thickness and volume to your hair in just a few sprays. Nanogen’s scientifically formulated Root Boost Hair Thickening Spray contains keratin, lifting polymers and a thickening combination of caffeine and soothing niacinamide to care for your scalp. Blow-drying your hair after applying Root Boost Hair Thickening Spray will activate more thickening protein, giving your hair even extra volume!


Root Boost Hair Thickening Spray is non-comedogenic, meaning it won’t block the follicles on your scalp and is suitable to use with minoxidil or any other topical scalp treatment. Free from parabens, SLS and formaldehyde donors, this anti-inflammatory formula is suitable for even the most sensitive of scalps.

Boost your hair’s electrostatic charge.

Ideal to use before you apply Nanogen’s Keratin Hair Fibres – this ingenious spray contains thickening polymers which alter the electrostatics of the hair to help it stay volumised, plus additional inherant properties also help to keep the charged fibres attached to the hair shaft!


Key Ingredients

Keratin – This natural protein provides hair with moisture, body and therefore an instant thickening effect. Rich in cysteine, the amino acid which gives keratin its unique strengthening and protecting qualities.

Niacinamide – An ingredient found more typically in advanced in skincare where it’s used to stimulate collagen production, it has purported anti-inflammatory properties. We include in Root Boost to help to exfoliate dead skin cells, soothe latent irritation and unclog hair follicles for a clearer ‘growth path’.

Green tea extract – This antioxidant powerhouse protects hair follicles from the inflammatory effect of free-radical damage, for a soothing effect and a healthy scalp.

Caffeine – Not just a great pick me up in the morning. it penetrates the hair root and is believed to help stimulate hair follicles for faster, stronger hair growth.

Provitamin B5 – Works as a humectant, attracting water from the air and utilising it to improve hair lustre and reduce frizz.

Mineral rich natural sea salt – Binds onto the base of the hair follicle and causes friction between hair strands for an effective life, texture and unparalleled volume.

Lifting Polymers – Clever polymer molecules land and then dry onto the root of the hair and then stiffen adding lift to the hair shaft.


Direction of use

Step 1 – Simply spray onto your damp roots for an intense root lift and boost.

Step 2 – Additionally, spray throughout your hair lengths, for maximum fullness throughout.

Step 3 – You can leave to dry naturally, or blow dry your hair to activate more thickening proteins.

Step 4 – For best results, use every time you wash or style your hair. Re-apply daily and/or during the day for a quick extra boost.
