I’ve been using this serum for 8 weeks and I can clearly see more volume in my hair. It feels light and doesn’t make my scalp oily. The texture is easy to apply and I use it every morning before styling.

It’s a noticeable improvement in hair density. I didn’t expect such a strong effect, especially after years of thinning. I apply it to the roots every other day and feel the difference in fullness.

It works for me, but I don’t see dramatic changes yet. I’ve been using it for 5 weeks and still need more time. I think it’s effective but results may vary depending on individual hair conditions.
