FREQUENTLY ASKED QUESTIONS
Discover how Kosean can give you the thick, radiant hair you’ve always dreamed of—without the stress or endless waiting.
How long will it take before I stop finding hair in the shower drain?
Most users report a significant reduction in hair loss within the first 2–4 weeks of daily use.
Will this make my hair oily or greasy?
Absolutely not.
It is designed so you can apply it to dry hair in the morning and start your day with a fresh, clean look.
I’ve already tried hair growth products. Why is this one different?
Most products aim to treat individual hair strands. We target the root.
Our serum uses a special Korean activating complex to help restore scalp balance and support inactive follicles, especially in thinning areas like the hairline and part.
How often should I use it?
For optimal results, apply the serum directly to the scalp once or twice a day.
Consistent use helps make hair healthier and thicker over time.
Can I use it alongside other hair products?
Yes. You can easily incorporate it into your routine alongside your shampoo, conditioner, and styling products.
