Love this product! First of all, it does NOT stink. the herbaceous fragrance reminds me of high-end Aveda products. It smells fresh and green and the mint...lovely. I have fine hair that is prone to break. After a few uses, I noticed that my hair appeared and felt much thicker. The mint tingles my scalp. The claim that it invigorates for regrowth...let's hope so, but my scalp feels renewed and healthy, and a healthy scalp clings on to the hair by the roots to prevent hair loss. I have not tried the shampoo or conditioner yet, but I plan to when my current stock runs out. Fine and thinning hair folks MUST try. It does not make hair feel sticky or dry like other root boosting products (and believe me, I have tried plenty) claim to. Please keep this line. I am happy to see such a wonderful product at such an affordable price.
