Great serum
[This review was collected as part of a promotion.] Have absolutely loved this serum - use it after the shampoo and conditioner on wet hair and massage into scalp. No irritation and no greasiness after- hair feels thicker and in best condition it’s been for a while. Love the pump on it too no mess

Makes me feel confident
[This review was collected as part of a promotion.] I use this serum on damp hair. It’s lovely as not a lot is needed when massaging in to your scalp. I have used this for almost 2 months and definitely seen improvements of hair feeling and looking more fuller and healthier. It’s my go to product and I wouldn’t go without it. I feel much more confident when styling my hair.

Ok
[This review was collected as part of a promotion.] [I received this product in exchange for my honest review] Its a nice shampoo but at first was a bit strong with the tingling. Very strong minty smell. I didn't find it helped with thickening my hair though which was a bit disappointing. Packaging looks professional and im not sure on the value for money. Unfortunately this time I wouldn't buy it again

Lovely feel in my hair
[This review was collected as part of a promotion.] I've tested this thickening serum for a few weeks now, and it seems to have helped my hair in being stronger. As for thicker, I'm not sure just yet. It definitely feels nice in my hair, maybe a little tricky to get straight onto the roots, but it grows through softly. The smell is minty, which is I love and doesn't stick in your hair too long.

Worth trying
[This review was collected as part of a promotion.] I’m happy with this product so far. I was waiting with review until I finish whole bottle of this serum and I can say now that my hairs are thicker. Scent is ok, not overwhelming and price is good too.
