LA BIOSTHETIQUE Growth Booster RT 95ml

A 95ml leave-in scalp lotion from La Biosthétique's Long Hair range, applied at the parting with a pipette and left in. It is scalp care for people growing their hair out, aimed at the skin the hair comes from rather than at the lengths.

What's in it

• Arginine, lysine and aspartic acid — amino acids that are among the building blocks of keratin.
• Glycogen and creatine — the formula's energy pair.
• Biotin and trace elements from coral moss.
• Wheat bran extract — formulated to help keep airborne particles from settling on the scalp.
• Apigenin, oleanolic acid and vitamin B12 round out the plant and vitamin content.

How to use it

Two pipettes' worth, distributed along the partings across the scalp and massaged in lightly with the fingertips. Leave it in — it is not rinsed. La Biosthétique recommends several applications across the week rather than one heavy one.

Worth knowing

The formula is non-oily, so it does not flatten the roots or leave hair needing an extra wash. It is cosmetic scalp care and it works on the scalp, so the lengths still need their own conditioning. If you are concerned about thinning or shedding, that is a conversation for your GP or a dermatologist rather than a bottle.
