Been using this product for several years. Use weekly this product helps balance my sometimes dry scalp and keeps my hair looking healthy. It works best when used in conjunction with the RF hydrating shampoo. Sometimes I apply at night and leave it on until the AM, then wash my hair. This is a “pre-wash treatment which I find works better the longer I leave it on my scalp. My hair feels incredibly soft and shiny after using this treatment. If left on the scalp for a more then 10 minutes it causes a warm sensation but this is not at all unpleasant. I have fine, thick blonde hair and started using this when I noticed some thinning on one side of my head. Have not noticed any “regeneration” of hair in that one area but I still love to use it because it leaves my scalp feeling healthy, reduces dry patches and I love my soft shiny, healthy looking hair after use. I’ll continue to use this product.
I have used this product twice so far (they recommend to use 1-2 a week) and my hair is already transformed. It has volume and no frizz at all. It is very soft and shiny. And it was so easy to style. I love the warm and tingeling sansation on my scalp after applying. Oil washes out with no problems. I used the Rene Furterer Curbicia shampoo after. Loooove my hair today:))))
