Thinning Hair? What Actually Helps: Shampoos, Serums and Supplements
Noticing more hair in your brush, a wider part or less volume than before? You are not alone. Thinning hair is one of the most common concerns our hairdressers hear from clients, women and men. Here is a practical look at what can help.
First, understand the cause
Hair can thin for many reasons: genetics, hormonal changes, stress, diet, illness, styling damage or breakage. If shedding is sudden or significant, see your doctor or a dermatologist first, since some causes need medical care.
Thickening shampoos and conditioners
A good thickening shampoo cleanses the scalp without weighing hair down and makes each strand look fuller. Popular choices include Kérastase Densifique Bain Densité, Kérastase Genesis Homme Bain de Force, and ACTIIV Recover for Women and ACTIIV Recover for Men.

Leave-in serums and scalp care
A healthy scalp is the foundation for healthy-looking hair. Daily leave-in serums such as ACTIIV Thickening Hair Serum or Viviscal Thin to Thick Elixir are designed for the scalp and roots. Browse our full scalp care collection for scrubs and tonics.
Supplements
Some clients add a hair supplement such as Viviscal Hair Growth Supplements. Supplements take time, usually several months, and are best discussed with your doctor if you take other medications or have health conditions.
Styling habits that help
- Use heat protection and lower heat settings.
- Avoid tight ponytails and buns that pull at the hairline.
- Detangle gently from the ends up, and swap rough towels for a soft or silk wrap.
- Get regular trims to remove breakage and keep ends looking fuller.
