Unbearable

I purchased this product a few weeks ago and tried immediately on dry hair/scalp...it made my scalp itch so bad it was unbearable, so I had to thoroughly wash it out. I thought maybe I would give it a second try while also adding the Nutri Supplement Scalp Serum directly after the Resistance serum, but the same unbearable itch occurred. This is by far the worst hair product I have ever used, and will never purchase anything from this company again.

i was happy with the two times i got to use it but because the bottle is so fragile dropped on carpet and broke basically loat all the product super upset think it should be in a container more sustainable then that and I buy a lot of lot of keratoses products
