FAQ
1. What does a scalp serum do?
A scalp serum targets the scalp to improve hair growth, reduce hair fall, and balance scalp health. It delivers active ingredients directly to hair follicles, helping strengthen roots, stimulate growth, and improve overall scalp condition.
2. Can scalp serums really help with hair growth?
Yes. Scalp serums with ingredients like Redensyl, Anagain, Capixyl, caffeine, peptides, and rosemary oil help improve blood circulation, reactivate dormant follicles, and extend the hair growth phase, resulting in thicker, healthier hair over time.
3. How often should I use a scalp serum?
Most scalp serums are safe for daily use. Apply once or twice a day, depending on the product instructions. Consistent use for 8–12 weeks is recommended for visible results.
4. Are scalp serums better than hair oils?
Scalp serums are lighter, non-greasy, and absorb quickly, making them ideal for daily use and oily scalps. Hair oils are heavier and better for occasional nourishment. For best results, use a serum daily and oil once a week.
5. Can scalp serums be used on oily or acne-prone scalps?
Yes. Many scalp serums are formulated to be lightweight and non-comedogenic. Look for ingredients like niacinamide, salicylic acid, tea tree oil, or zinc to help control excess oil and prevent buildup.
