I have my hair in crochets but I use the serum in the parts and massage. But I do feel tingling in the scalp. My own corn rolls are loosening as I am getting new growth. To be fair, I am using another ptoduct as well which I was using before the serum. I will let you know the results when the crochets come out.

I've been using AcneFree Severe for a year and a half. However, I would never recommend anyone with sensitive or dry skin to use the CLEANSER and the TONER - instead y'all should substitute them with the Cetaphil cleanser (much more gentle for sensitive skin.) I would use the smallest triangular bottle in the AcneFree kit on my pimples during the night and the maximum repair lotion for my pimples during the day. I use them with an organic moisturizer and I think they show the best results that way. Although the 2 cream did not make my pimples disappear straight away, they definitely dry them up and reduce some redness (also decreasing them in size.)

Works great, just as described. It stopped my leak within 24 hours. I suspect that those who say that it does not work waited too long to try it. In my case my leak was around 6 or 8 drops on my garage floor a day for several months before I used it. If you are leaking a quart of oil a month then who knows but you may be too late for it. No damage to the engine as the cars runs as well as ever.
