Hair Serums

There are two types of hair serum in this range. Finishing serums smooth frizz, add shine and often protect from heat: Kérastase, Davines, Paul Mitchell, BioSilk and Goldwell are the main brands. Scalp serums are water-light leave-in treatments applied to the roots, often with peptides, caffeine or rosemary. Most cost between £28 and £49.

Use finishing serum sparingly on mid-lengths and ends of damp or dry hair, and one or two drops is enough for fine hair. Scalp serums are applied directly to the scalp along partings and left in. Check the title to see which type a product is.

Frequently asked questions

When should I apply hair serum?

Smoothing serums go on damp hair before styling or on dry hair as a finishing step. Scalp serums are usually applied once a day to a clean scalp and not rinsed.

Will hair serum make my hair greasy?

Not if you use a small amount and keep it away from the roots. Fine hair does best with lightweight, non-greasy formulas.

What is the difference between hair serum and hair oil?

Serums are usually silicone-based and coat the surface for smoothness and shine. Oils are plant-based and mainly add softness and nourishment.
