I recommend Nineless Scalp Scrub Shampoo.

Last winter, I noticed a few flakes of dandruff, and as time passed, the amount increased. Thinking a scrub might help, I purchased this product after reading online reviews. It is a scalp scrub from Nineless. First, you just need to thoroughly wet your hair, apply it to your scalp, rub it in, leave it on for a moment, and then rinse it off. I made sure to rinse it very thoroughly. After doing this about 2-3 times, my scalp felt refreshed, and the dandruff gradually decreased. Now, I use it about once a week. I recommend this to anyone struggling with dandruff.
