My hair is thinning badly due to low iron and a 100lb glp-1 weight loss. It has been a very depressing time. My hairdresser said a lot of her clients were having luck with this - and WOW! It’s amazing. My hair feels healthier and is definitely thicker, enabling me to style it to cover the thin or bald areas. Combined with a Nutrafal regimen, I have had real growth and am finally feeling better about myself. Give it a try if you suffer with hair loss like me!

It's a great product. I find it really works. It's unscented. My hair is thicker. I would definitely buy this again. Update...it's full of caffeine which I am allergic to. Made me very ill. Buyer beware. There should be a warning ⚠️ on the label!!!

I bought it for my postpartum hair loss. My hair were falling out like crazy but after using this product it stopped and I actually have lots of baby hair. I thought the product will be oily but it is more like just a liquid and it doesnt leave hair greesy.

If you already love this product, buying it this way is a great value. Having it delivered right to your door is incredibly convenient. I’ve noticed that it seems to support healthier hair overall — helping with breakage and making my hair feel stronger. It also appears to promote better growth by supporting the hair at the root. Overall, a convenient and cost-effective way to keep this staple on hand.

Price is too much. But it helps. It is not comparable to head and shoulders tonic but unfortunately it is discounted.
