Thinning hair? These Labor Day deals for fine strands start as low as $6

Our writers dubbed Nutrafol the best overall hair growth supplement for women, writing that "Nutrafol Women's Balance is a little pill that delivers mighty results thanks to a wide variety of vitamins, minerals, and amino acids, plus botanicals like horsetail, marine collagen, and solubilized keratin. 

Nutrafol's hair growth products are formulated to address the root causes of hair thinning and loss: hormones, stress, lifestyle, metabolism, nutrition and aging. As a bonus, many of its nutrients will support your overall health, including lowering stress and helping you sleep.

It might seem like hooey, but it's actually true: Topically applied rosemary oil has been clinically proven to initiate new hair growth and help prevent further loss. In fact, a 2015 study suggests that rosemary essential oil is as effective as minoxidil at growing new hair in mice.

This is an excellent, highly-rated rosemary oil should you want to try it out — it's also an Amazon No. 1 best seller too with more than 70,000 5-star reviews.

One big problem with fine, thin hair is that it's hard to find moisturizing, defrizzing products that won't make your strands look limp. Enter OGX's weightless dry oil spray, which helps smooth fly-aways, mend split ends and eliminate that fuzzy, frizzy summer-hair look without looking greasy or heavy.

"This oil is extremely lightweight, does not weigh down hair and the spray bottle projects the perfect amount in each spray," said one reviewer. "I have fine hair and it is perfect. Leaves my hair soft, not greasy, and there's no lack of volume. Hair is soft, has volume and protects against humidity and has a very light minimal scent."

At first glance you might think: Why in the world would I need a silk pillowcase? AM I AN EMPRESS? Are we in Hollywood in 1934? Should I start sleeping in a face of cold cream and calling people dah-ling? Do I need a silk robe and high-heeled slippers too?

But then you learn the facts: Silk pillowcases support the health of both skin AND your hair. Research shows they can help prevent shedding and breakage and can keep your hair from frizzing overnight, leading to less styling and an overall healthier mane.

Some forms of hair loss can be caused by product buildup on the scalp and, if your hair is both shedding and looking dull, Neutrogena's Healthy Scalp shampoo may offer relief. It's non-medicated, color safe and sulfate free and, while the formula is strong enough to dissolve built-up gunk on your scalp and strands, it's not too harsh to be used occasionally on fine or thinning hair.

Best of all is the grapefruit scent, which is citrus-y and fresh but not at all sweet. 

Boldify's Hairline Powder is not only one of our best gray roots touch-up products of the year, it's also quite good for filling in a sparse hairline. If you have silver roots and you're suffering from thinning hair, this might just be your ticket. It's not as harsh as some of the spray formulations and it's easy to wash out — all of which is crucial for maintaining fine, thinning hair and helping stave off additional shedding.

The shade range here is impressive — there are 14 to choose from, including three blonde. There's even a silver option, if you're interested in maintaining your grays while filling in patchiness and making your coif look more robust. Last surprise bonus: The powder works a bit as a dry shampoo to absorb excess oil so you can shampoo less. 

Thinning hair? After publicly sharing her post-COVID hair-loss story via video on Twitter, actress Alyssa Milano found the help she needed within a few bottles. She praises Nioxin products (and Nutrafol supplements too!) for helping "tremendously" with hair loss. And she's not alone: These products have found fans in shoppers who say the treatments have helped curb their own hair loss and revitalized their manes. 

"Great for thinning hair," gushed a satisfied shopper. "I love this brand, and for thin hair, it's wonderful; smells amazing and helps [with] my hair growth and thickness. If you have never used Nioxin, you should!"

There's so much to love about this thickening, moisturizing, salon-quality shampoo and conditioner duo. For starters, it contains zero harsh chemicals. It's safe for all hair types (including color-treated) and it's not tested on animals. But the ingredients are the true stars here: Biotin, vitamin B and caffeine are all proven to nourish fine hair follicles and help stimulate growth. 

With more than 10,000 five-star reviews, this popular set is a steal at 30% off. "My hair has never felt so good," said one reviewer. "My hair is thin but this does not weigh it down. I also notice a lot less hair loss in my brush and styling tools."

This lightweight, scalp-health-boosting spray was developed with the help of dermatologists to bring volume, bounce and lift to even the thinnest hair.

It's formulated with vitamins B and E, plus nourishing peptides to texturize hair at the roots without making it crunchy or dry like many treatments of its kind. The result is soft, silky, fuller hair — for under $10.   

"I was looking for a product with root lift that didn't make my scalp itchy or sticky feeling," said a fan. "This is a very good product. Smells nice. It also doesn't make my hair greasy, so I can go a couple of days without washing. I don't need extra product each day either."

File this silicone brush under "things you don't think you need until you try them." And, if you have thinning hair, regular scalp massages are one of the best and first steps to take if you want to stimulate growth.

This tool makes it easy — just apply your shampoo or hair oil and go to town in circular motions for a minute or two. Not only will you be helping to unclog pores on your scalp and improving circulation, but the whole process just feels good — both invigorating and head-clearing. 

More than 5,000 Amazon reviewers give this aerodynamic brush 5 stars; many were especially keen on the thoughtfully designed, easy-to-grip handle. As a bonus, the deal also includes a handy satin scrunchie.
