I started using Dr. Miracle's 2 in 1 Tingling Shampoo and Conditioner about 6 months or so ago. I'm thankful that I decided to purchase this product. I fell in love with Dr. Miracles 2 in 1 the first time I tried it. Just like the name says, Dr. Miracles 2 in 1 Tingling Shampoo and Conditioner does leave your head tingling. My scalp felt revitalized and it lasted for quite some time. I've never tried any shampoo or conditioner that leaves your scalp feeling this good. Dr. Miracles 2 in 1 Tingling Shampoo is a special product made for "black women" or women of color. It states on the product that the Doctor used some old folks remedies/potions that produces the tingling sensation. It feels like having a "head massage" with a special potion applied. Within the last six months, my hair has grown in length, showing that this Dr. Miracles Shampoo and Conditioner does work. I will continue to buy this product and would recommend to any Afro-American that hasn't tried it. You just might like it. Effectiveness It cleans and conditions. Dr. Miracles 2 in 1 Shampoo and Conditioner does leave your head tingling. Scent I like the smell of this product although it does not have a lot of fragrance lot some shampoo and conditioners.
