Reddit mentions of Biotique Botanicals Bhringraj Hair Growth 120ml

Biologist here - that is absolutely a scam. I could tell you that even without my expertise - look at that website! It looks scammy because it is - generalized claims, anecdotes, and a general lack of information. Looking at their FAQ, I see that their main ingredient is Eclipta alba. Cruising over to wikipedia, I see that a related species. E. prostrata was actually found to influence hair growth...but looking further at the research, it influenced which growth phase the follicles were in, not the actual rate of hair growth. For more information, please see this Yahoo! questions answer (yea, I know YQ is generally awful, but this answer is actually really superb.)

Hair grows about 1cm a month, but the exact rate at which it grows is largely determined by genetics. There are certain exogenous factors that can influence hair growth or hair loss which act on hormones (androgen) or ion channels (potassium.) Some products like rogaine do influence hair growth but that has more to do with regulation of hair growth phase and not the rate at which the hair grows. You'll also see sites like this around. All of these things can influence how your hair grows in (they can help improve the strength/thickness/etc and prevent breakage or follicle turnover) but, despite claims, they likely do not influence how fast it grows in.

Aside from the fact that this hair oil references nothing of the sort, I would say it is absolute bunk because the claims of 2-3 inches/month are absolutely ridiculous from a biological standpoint. Your cells in your follicle can only divide so fast, and they can only produce keratin so fast!

Please please please do not waste your money on something you can probably get a lot cheaper. If you really want to see if any of those ingredients do work, buy them individually. I can easily find bhringraj oil (made from E. alba) for $4.40 on Amazon.
