As someone who feels like my hair grows at a snail’s pace, I can relate to the frustration. Add to that the alarming amount of hair I seem to be losing—it’s more than my two big dogs combined! After each shower, I dread looking at my hairbrush. Is it stress? Aging? But then I discovered this budget-friendly shampoo on Amazon that claims to stimulate hair growth: the Marc Anthony Grow Long Biotin Shampoo. Could it really be as good as it sounds? I decided to find out.

This shampoo is sulfate-free and contains caffeine, ginseng, and vitamin E—ingredients that are said to nourish hair, reduce breakage, and promote growth. A study published in the International Journal of Dermatology found a connection between caffeine and hair follicle stimulation. But what are actual users saying?

First off, the shampoo boasts an impressive 6,900 five-star reviews. One customer exclaimed, “I can’t believe how much my hair has grown in just a month—I’d estimate it’s about an inch longer! My daughter was shocked at how much it had grown in such a short period.” Another positive review states, “Using the Grow Long shampoo and conditioner leaves my hair feeling clean and soft, with no tangles. I believe it’s improved the texture and thickness of my hair, and I notice less fallout.”
