Hair loss and thinning hair are fairly common issues for men, but the problems are somewhat stigmatized among women. However, the American Hair Loss Association explains that 40 percent of American hair loss sufferers are women. Due to the prevalence of female hair loss and thinning hair, many shampoo products designed to address these problems are available. In order to find the best one for you, consider the reviews of these products and try to understand shampoo ingredients and their use.

According to the hair care website World of Hair, Boost Super Stimulating Shampoo is a top seller for thinning hair in women. World Of Hair explains that Boost shampoo is effective because it blocks the hormones that cause hair loss in both men and women.

Boost also offers a Super Stimulating Conditioner to be used in conjunction with the shampoo.
