A 3-week vial cure for thinning hair and hair fall
Biocyte Keratine Forte Serum is a leave-on scalp serum for anyone dealing with hair fall, thinning or dull, weak hair. It combines four actives, each with its own role. Anagain, a patented pea sprout extract, works on the hair cycle to reduce hair fall and support new growth. Legactif, a second patented active, boosts microcirculation in the scalp for a revitalising effect. PQQ supports the energy of hair follicle cells, and hydrolyzed keratin, the main building block of hair, strengthens the fibre. In Biocyte's tests, 95% of users noticed less hair fall and 85% noticed more growth.
How it works
Each 9ml vial has a soft applicator tip and holds three doses, so one vial covers three days. The liquid is applied directly to the scalp and left on, without rinsing. It is light and does not make hair greasy when used on a dry scalp after washing.
Who it suits
- Early signs of hair fall or seasonal shedding
- Sparse or thinning areas
- Hair lacking strength and vitality
- Anyone wanting a short intensive cure or regular upkeep
Worth knowing before you buy: The serum contains fragrance and is not suitable if you are allergic to any of its ingredients. Once opened, a vial should be used within 7 days. This 15-vial pack covers a full intensive cure in one box.
How long the pack lasts
One vial lasts three days, so the pack of 15 covers about 45 days of daily use, enough for a full 3 to 6 week cure. For maintenance, one vial a week makes the pack last almost four months.
