Hair serums are one of the most powerful treatments in any hair care routine — designed to smooth frizz, repair damage, and add a glossy, healthy finish. At Welzo, our curated range of hair serums includes nourishing formulas for all hair types, including fine, dry, colour-treated, or damaged hair. Whether you’re fighting humidity, heat damage, or dullness, the right serum helps protect and transform your strands.

Unlike oils or leave-in creams, hair serums are typically silicone or water-based and sit on the surface of the hair — sealing the cuticle, shielding against pollutants, and locking in moisture for a weightless finish.

What Does Hair Serum Do?

Hair serums are multitasking products that:

• Tame frizz and flyaways instantly

• Protect from heat styling and UV damage

• Add shine without greasiness

• Reduce split ends and dryness over time

• Smooth the hair shaft for a silky finish

• Strengthen and condition hair that’s chemically treated or over-styled

Serums are especially helpful after washing with a sulphate-free shampoo, or before using hair styling tools.

The Best Hair Serums for Your Hair Type

At Welzo, we stock a wide selection of targeted serums, including:

• Frizz control serums – Ideal for humid weather or naturally frizzy hair

• Shine-enhancing serums – For dull or dry hair that needs a glow boost

• Repair serums – With keratin, argan oil or peptides for damaged or coloured hair

• Lightweight serums for fine hair – That won’t weigh your hair down

• Scalp serums – Designed to nourish roots and support healthy hair growth

Pair your serum with a matching hair conditioner or use it after applying hair colour removers to help restore lost moisture.

Concerned About Hair Thinning or Breakage?

If you’re using hot tools daily or noticing more hair fall than usual, serums can offer both instant protection and long-term strengthening. For deeper issues such as thinning, patchiness or hormonal shedding, explore our Hair Loss Treatment options — including clinically backed products like Regaine, Finasteride, and our hair growth red light devices.

You can also support internal hair strength with targeted hair, skin and nails vitamins or vitamins for hair growth.
