Biotin (Vitamin B7), in turn, helps stimulate the synthesis of its own keratin to form a healthy and strong hair structure, reducing hair loss and preventing breakage and split ends.

THE DOCTOR Juukseseerum Keratiin, arginiin ja biotiin 89 ml by Elfa Pharm is a leave-in hair serum for weakened, thinning hair that looks fragile, breaks easily or seems less dense than before. People usually choose this type of scalp and hair serum when they want a lighter alternative to rich oils: something that helps the hair feel stronger, smoother and more resilient without leaving a greasy film.
The formula combines three well-known actives that work in different ways. Hydrolyzed keratin is keratin broken into smaller fragments, so it can coat the hair more evenly and temporarily fill rough, damaged areas along the shaft. This helps the lengths feel smoother, look shinier and snap less during brushing. Arginine is an amino acid often used in scalp products because it is linked with better microcirculation in the skin, which is why it is often included in formulas aimed at hair roots and vitality. Biotin, also known as vitamin B7, is valued in hair cosmetics for helping maintain the condition of the hair fibre and for its role in keratin-related processes.
What makes this Elfa Pharm hair serum practical is the balance between scalp-focused and length-focused ingredients. It is not just a styling gloss for the ends: it is meant to be applied to the scalp and then distributed through the hair. Humectants such as glycerin, betaine and urea help bind water, so the hair feels less dry and the scalp feels less tight after washing. The lightweight texture absorbs quickly and does not need rinsing, which makes it easy to use after shampooing when hair is more vulnerable to mechanical damage.
This serum can fit well into a regimen for hair that is stressed by frequent washing, heat styling, colouring or seasonal shedding. It suits those who want hair to look fuller and more polished while also giving attention to the scalp. With regular use, the main visible benefits are usually easier combing, less roughness through the lengths and a stronger-looking finish rather than an instant dramatic change in hair density.
As with any active scalp cosmetic, it is wise to watch how your skin responds, especially if your scalp is sensitive or easily irritated. Avoid applying to damaged skin, and if you are experiencing sudden or pronounced hair loss, persistent itching or scalp discomfort, it is best to ask a pharmacist or healthcare professional for individual advice.
