Why does hair loss happen? Outside of genetics, life phases can be the cause. Menopause can result in a number of unpleasant symptoms such as hot flashes or insomnia. However, one side-effect that many overlook is thinning hair and hair loss among middle-aged women. Estimates show that about 40 percent of women over the age of 60 will develop female pattern hair loss, or androgenetic alopecia. 

Something you can control though is how much fat you eat and the number on the scale. A recent study revealed that too much fat in your diet can also be bad for your hair. Researchers from Tokyo Medical and Dental University discovered that a high-fat diet accelerates hair thinning and hair loss as we age. Obesity also contributes to less luscious locks. Here’s why: In studies using mice, obesity introduced certain inflammatory signals to the body, blocking hair follicle regeneration and eventually leading to the loss of the follicles.

Sometimes hair loss is normal, like after pregnancy or with age. But if you have what you’d consider an excessive amount of lost strands, consult with a medical professional to diagnose the root of the problem. If you’re just wanting to give your hair a boost, reach for the best shampoo for thinning hair. Below are the top five expert-recommended products for you to try. Let us know in the comments if we missed your tried-and-true favorite!

The List: Best Shampoos for Thinning Hair, According to Experts

1. Pura D’Or Original Gold Label Anti-Thinning Shampoo

PureWow says you’ll see results: “Shown to result in less hair shedding after just eight weeks, this potent formula also promotes volume and hydrates dry strands. It’s jam-packed with vitamins, amino acids and oils (like black cumin seed oil) to reduce thinning. But it’s the over 17+ DHT herbal blend that nourishes, cleanses and protects the scalp after every wash.” 

“This PURA D’OR Original Gold Label Anti-Thinning Biotin Shampoo is great for thinning hair [and] helps promote thickness and combat breakage with its impressive formula, which is enriched with ingredients (including rosemary oil, argan oil, and tea tree oil) that assist with promoting hair growth,” claims Insider.

“With nearly 17,000 five-star ratings under its belt, this biotin shampoo comes highly recommended from Amazon shoppers and Dr. Liia Ramachandra, a skin care expert and former pharma executive. She says. ‘This formula is packed with a powerful blend of biotin, nettle extract, pumpkin seed and black cumin seed oil.’ The hypoallergenic, gluten-free shampoo promises to reduce hair thinning by strengthening and thickening strands, adding volume for days and reducing breakage along the way,” according to TODAY.  

2. Paul Mitchell Tea Tree Scalp Care Anti-Thinning Shampoo

Allure likes this plant-powered formula: “This color-safe Paul Mitchell Tea Tree Scalp Care Anti-Thinning Shampoo, which boasts a mixture of kakadu plum, pea peptides, clover flower, turmeric, and ginseng. These powerhouse ingredients, along with anti-inflammatory tea tree oil, work together to cleanse and strengthen the scalp for thicker hair down the road.” 

“This powerful shampoo contains a hardworking trio of turmeric, ginseng, and kakadu plum that works to expand each strand to give the appearance of fuller hair and reduce breakage each time you wash,” writes Oprah Daily.

And The Strategist says, “If your hair is both fine and thinning, trichologist Rochelle Hunter Mosley likes this shampoo from Paul Mitchell. With thinning hair, the shampoo you use is extremely important because you need it to add both body and volume, body, as well as shine, something this shampoo delivers, she says.”

3. Shampoo by Blu Atlas

Orlando Magazine suggests using this every day forever. “If you could pick just one shampoo for the rest of your life, this shampoo should be the one because of its supreme benefits. The shampoo is formulated with vegan ingredients and a blend of saw palmetto, biotin, jojoba protein and aloe vera. In a short time, your hair will take on a new, refreshed look and feel stronger and healthier than ever before.” 

Observer is hopeful this shampoo is for you: “If you’re hoping to get thicker, stronger hair without weighing it down, Blu Atlas is the shampoo you’ve been looking for. This shampoo strengthens hair and prevents oil buildup with potent natural ingredients, making it the finest option for men with thinning hair. Jojoba oil is rich in beauty-boosting vitamins A, E and D, as well as antioxidants and fatty acids.” 

“In this 99% naturally-sourced shampoo by Blu Atlas, you’ll find potent botanicals and plant extracts that help strengthen hair and prevent oil buildup on hair and scalp. Aloe vera leaf juice provides the scalp with necessary nutrients like vitamins A, C, and E; it also hydrates and calms so your scalp is prepped and primed for healthy hair growth. Other star ingredients include jojoba protein, which locks in moisture, conditions, and repairs damaged hair,” reports Men’s Journal. 

4. Biolage Advanced Full Density Thickening Shampoo

Byrdie says this product will reduce breakage, writing, “This pick gets top honors for taking a two-pronged approach to thinning hair. First, it goes to town by gently removing follicle-clogging impurities that can impede new hair growth. Then it delivers a host of important nutrients — biotin, zinc, and a gluco-omega blend — to strengthen the hair you have. So much so that, when used with the accompanying conditioner, it can reduce breakage by up to 95 percent.” 

Cosmopolitan says, “This gentle shampoo earns [a] spot on this list due to its ability to remove build-up that tends to clog hair follicles and create a less-than-ideal environment for hair growth. Your hair will feel thicker, but it’ll also look healthy and shiny. Not to mention, it’s safe for color-treated hair, which is a win-win in my book.” 

5. Ouai Fine Hair Shampoo

Forbes chooses this cleansing shampoo as a great option: “This cleanser packs biotin to fortify hair growth and structure as well as keratin for the same structural benefits (alongside softening, boosting shine and smoothing frizz). It also has chia seed oil to visibly plumpen and volumize strands, making it one of the best short- and long-term picks on the market today.” 

“This color-safe gel shampoo by celebrity hairstylist Jen Atkin offers a combination of biotin, hydrolyzed keratin and chia seed oil to help thicken hair. ‘Sebum secretion is that oil that makes your hair look greasy, so this [shampoo] helps control that, and it also fights frizz,’ said makeup and hair artist Francesca Maria Alfonso. It received a 4.4-star average rating from 1,429 reviews on Amazon,” addsNBC News.

Editor’s Choice: Hawthorne Thickening Shampoo

“Seeing my hair become significantly thinner in recent years has been a tough slap in the face when it comes to aging. Yep, it’s just one more realization that I’m over the hill. I’ve tried different thinning shampoos in that time, including some of the very expensive bottles. Sometime last year I gave Hawthorne a shot, and it can’t be pure coincidence that my hair feels and looks thicker than it’s been in quite some time,” says StudyFinds Editor-In-Chief Steve Fink.

“Besides the pleasant woodsy scent that isn’t too overwhelming (I hate any shampoo that I can smell on my pillow or just from moving around at any point), I don’t need to use too much to get a solid lather, even for having longer hair. I have no plans to give anything else a try for now. At about 12 bucks a bottle, Hawthorne is getting the job done, and well.”
