Beware, causes hairloss
This made my hair fall out right after the first use of shampoo/conditioner with this add-in vial and 2 others ones. Tried it again and my hair fell out again, it was a noticeable amount. I am so upset bc I am trying to grow back my hair fall out from postpartum and this just made things worse. I couldn’t return since I had tossed the empty vials. I ended up trashing the product. Never Again

Significant hair Lloss after I started using
I added this to my current shampoo routine, and began to significantly loose hair. I would just brush my fingers through my hair and a bunch of loose hair would fall out. As soon as I stopped using it I stopped losing hair.

Magic for your hairline
I noticed some thinning around my temples, so I added this to a leave in conditioning spray and applied to the thinning areas a few times a week. I noticed new hairs sprouting immediately….and I mean immediately. I now use it this way regularly on my hairline and my baby hairs and sideburns are in full bloom. I will never be without this product.

strength indeed
Such an innovative idea for shampoos as per need and it is affordable too?!! I am hooked. This bottle comes in a good size to last long and lathers well. I have to use it more to find how it affects my hair long term but it felt like my hair feels strong. gifted by functionofbeauty.

No difference
I received this gifted by Function of Beaty x Target. This particular enhancer didn’t do anything for me. Maybe I need to use it longer but I didn’t notice a difference. The concept is def cool but no changes

Grow baby Grow
This lengthen booster shot was gifted to me by Function of Beauty x Target. For kinky coily 4c hair, length is one of the struggles we face. This lengthen booster shot specifically takes care of that. I mixed mine with the moisturizer and I am excited to see the results over time.

I was gifted by Coily Hair Custom Shamppoo and Conditioner With Hairl Goals and when it comes to smell I love it.. Not to mention the volume it gives it and bounces. Will definitely recommend to family and friends. Makes your hair moister and shine perfectly.

Great
These hair boosters are so interesting to try and a great idea as well! They are easy to use and I like that it would work for sensitive skin as its fragrance free. My only criticism is that it’s not super obvious to me that it’s a two pack when both capsules are folded together in the box like that, I initially thought it was just one globe you cut for the bottle, so maybe separating the capsules in the box would make it more obvious. I received this product complementary from function of beauty X target
