I started using this on my hairline and noticed a difference in texture after a few weeks. It feels light and doesn't leave a greasy residue which makes styling so much easier.
Finally found something that fits my busy schedule. I just tap it onto my scalp while getting ready and it has helped my hair look and feel so much healthier lately.
Using this daily in my bathroom routine has been a game changer for my confidence. My hair feels thicker and healthier, and the rosemary scent is a lovely touch.
It is so convenient to keep in my work bag for a quick refresh. I love how it makes my hair look fuller when I am heading out for dinner after a long day.
