"I didnt use it long enough to see the effect but it feels nice. But the bottle has an issue because it leaks when it's laying on its side"
"Since using this serum, I've noticed a significant reduction in dryness and flakiness, which were persistent issues for me. The serum effectively locks in moisture and helps restore the natural balance of my scalp, making my hair feel healthier overall.
