### ⭐⭐⭐⭐⭐ It does the job!

### ⭐⭐⭐⭐⭐ It make a difference

Great love it

### ⭐⭐⭐⭐ Works, but using this product will take practice
*by B***M on December 23, 2025*

I was looking for a little help with hairstyling and decided to give this 'hair building fiber' product a try. The Caboki won out over competitors because first, it's not terribly expensive for a decent quantity of product and includes an applicator (whereas many others only have shaker tops). I've only used it a couple times and so far it does seem to work, although I need more practice to get it evenly applied, without any overspray. The product claims to be providing a 30-50 day supply, which seems reasonably truthful as far as I can tell. And yes, when applied, it does take very fine hairs and bulk them up, which helps those with thinning hair.
