I Tested 20 Top-Rated Shampoos for Thinning Hair Over the Span of 6 Months—These Are the 9 Best

Between postpartum hair loss and the stress of the pandemic, my hair has seen better days as of late. And I know I’m not alone. Hair loss in women is becoming more and more common. There are more serious medical conditions that cause this, like alopecia, but stress, diet, pregnancy, aging, and hormonal changes related to menopause can also cause thinning hair for a growing number of women.

“Your hair is a marker of your health,” says New York City-based trichologist and hair expert Shab Reslan. “If you have a poor diet lacking in animal protein and essential nutrients such as zinc, magnesium, vitamin A, iron, and B vitamins, your hair will not grow optimally and you could be weakening the cells in your hair follicles that are responsible for growing hair,” adds Reslan, who is launching a hair retail concierge platform for women to determine the best course of action for their hair issues.

The surge of women seeking advice from their dermatologists and hairstylists about this issue has led to an explosion of beauty products that claim to help slow loss, revive the health of your scalp, and help treat the symptoms of hair loss, like a lack of volume. “For women, if you’re experiencing a shift in your hormones, like getting off birth control, postpartum, or menopause, it is very common to experience temporary hair fall due to the irregular change in estrogen,” says Reslan.

There are no miracle products for hair loss, especially if it’s related to a larger medical issue, however, there are treatments and shampoos available that will help minimize the appearance of the condition. “A shampoo cannot single-handedly be responsible for growing hair back in, but instead should contain gentle cleansing agents to ensure a healthy scalp environment free of irritation and flakiness,” says Reslan.

“Gentle cleansers are very important in a shampoo, specifically for thinning hair, as the scalp needs protection and special care. Harsh cleansers such as sodium laureth/lauryl sulfate strip and irritate the scalp and hinder healthier hair growth. I recommend using only gentle cleansing agents that are safe and effective such as sodium lauroyl sarcosinate and cocamidopropyl betaine,” adds Reslan.

A little bit about my hair

I’ve always been told my hair is very fine, but since I had a lot of it, it appeared healthy and full. But since having a baby in 2019 and the stress of raising a toddler during the pandemic, I’ve experienced steady hair loss for the last three years. Recently, trichologist William Gaunitz told me I’d lost a large percentage (upwards of 30 percent) of the hair I once had, and showed me with a high-powered camera how inflamed and flaky my scalp was and continues to be to this day. Below, I ranked the shampoos that did the most work for my hair—and some of them are even on sale. You’re welcome.

Using this shampoo made my hair soft and shiny, and the smell was one of the favorites that I tested. I felt like my hair was stronger after using this just a couple of times. It’s definitely a worthwhile splurge in my opinion.

Foligain Triple Action Shampoo For Thinning Hair — $20.00

With over 500 reviews on Amazon, this product has 4.3 stars and customers rave about how they have noticed a difference in the fullness, texture, and growth of their hair.

In my testing phase, I noticed that this isn’t a super bubbly shampoo, instead, it’s a rich, creamy lather. Since it’s not very sudsy, I did have to use more shampoo than I normally do. However, despite the 2 percent Trioxidil, which has been clinically proven to slow hair loss, it doesn’t have a harsh chemical smell. Additionally, there are no parabens, sulfates or phthalates.

Since the instructions are to massage the shampoo on your head for a few minutes to stimulate growth, you’re basically forced to give yourself some self-care, something that I appreciated.
