This order was fine. I’m missing the previous 2 orders as they were sent to the wrong address. I addressed this issue and was told that I would receive the orders I paid for. They never arrived. Please follow up and let me know. I love the products and wish to continue receiving them. Thanks Mary Kelly

It’s so light that it doesn’t weigh down my fine thin hair. I have been using this for about 2weeks and my scalp feels less dry and my hair is already soft amd shiny. I also started using the rosemary shampoo amd conditioner at the same time and i love all the products. I definitely will continue using.

I take hair vitamins, Minoxidil, and have used many thickening shampoos and conditioners. Nothing helped the thinning at my crown until I used this serum. It is amazing.
