## Long description

Ziaja Welwetowe hair serum is a 50 ml leave-in treatment formulated to add shine and smoothness to hair while reducing frizz. Designed for use on damp or dry hair, the lightweight serum targets mid-lengths and ends to improve surface gloss and manageability without weighing hair down. The product is intended for regular use to help protect hair from humidity and create a polished, sleek appearance.
Advantages
The serum provides visible surface shine and helps control frizz with a light, non-greasy texture. It smooths hair cuticles to enhance gloss and make styling easier, while its leave-in formula allows for quick application and ongoing protection against humidity.

How to use
Dispense a small amount of serum into the palm, rub hands together and apply evenly through mid-lengths and ends of damp or dry hair. Start with a pea-sized amount for short hair and increase slightly for longer or thicker hair. Do not apply directly to the roots to avoid weighing hair down. Style as usual after application; the product is compatible with heat styling and everyday grooming.
Usage recommendations
For best results, incorporate the serum into a regular hair-care routine: apply to towel-dried hair before blow-drying to enhance smoothness, or use on dry hair to tame flyaways and add final shine. Adjust the amount according to hair length and thickness to avoid build-up.
