Frequently Asked Questions

Do hair serums really work?

Yes, especially if you style your hair regularly. A hair serum forms a protective layer over the hair, protecting it from environmental aggressors. It also optimizes scalp conditions, which, in turn, improves the quality of hair.

Can we use a hair serum daily?

Preferably not. If you have very frizzy and unmanageable hair, you can use an oil-based serum everyday. It is best to limit the use of serums for days you wash your hair or for special occasions and hairstyling.

Is a hair serum harmful?

Hair serums with silicones can be harmful in the long run if used excessively. The chemicals in some serums can cause the hair to dry out and lead to breakage. However, it is important to remember that serums primarily coat the hair shafts and do not penetrate the scalp. Hence, they will not cause harm if used correctly and in limited amounts.

Does a hair serum stop hair fall?

Not primarily. A hair serum coats the hair shafts and does not penetrate the cuticles like oil. It does not change the structure of the hair. Instead, it controls frizz and enhances curls. A nourishing serum gives you healthier hair, which, in turn, could reduce hair fall.

Can a serum help hair grow?

Not all serums promote hair growth. However, they may encourage the follicles to produce shinier and thicker hair. This may make your hair look fuller.

Where do you apply hair serum?

Apply it to the hair strands. Avoid direct application to the scalp to avoid a greasy look.

What comes first: oil or serum?

Serum comes first. Hair serum should be used after the hair is washed and towel-dried. If required, a little oil can be applied after the serum for a better finish for very dry or frizzy hair. Keep oil away from the roots to avoid a greasy look.
