Will this shampoo make my hair grow or stop it from falling out? — MODUM KLASSIKA Beer Yeast Shampoo, 550 ml

No shampoo can honestly promise to change how quickly or how much hair grows, and this one does not. It is a cosmetic cleansing product, not something intended to influence hair growth or hair loss. The brewer's yeast ingredients are there for the look and feel of the hair fibre, not for changing what happens at the root.

When the product description mentions a denser look, that is an appearance effect. Hair that is cleansed, smoother and less limp can seem fuller because the strands separate better at the root and reflect light more evenly. That can be a welcome change if your hair looks flat, but it is not new growth.

If shedding becomes heavier than usual or hair thins in patches, a shampoo is not the right tool for that concern. You can still use this product as your routine cleanser while you discuss the issue with a specialist, but keep expectations realistic: its job is to make the hair you already have look and feel better.
