Adam Federico, R+Co director of content, recommends using this thickening shampoo which tons of nourishing ingredients to help your hair grow strong and healthy. It features a blend of biotin to help increase your hair strength, as well as vitamin B5 and coconut oil, both of which add a glossy sheen. Add to that saw palmetto extract (which adds body), and this all-natural and eco-friendly shampoo makes your hair look fuller while helping it grow at the same time.

Speaking of the formula, Federico says, "Biotin, which is an ingredient in DALLAS, improves the internal structure of the hair. This improved structure can help to prevent snapping and breaking."

Federico also suggests using this thickening condition in conjunction with the thickening shampoo. It's made from a luxe blend of biotin, saw palmetto, vitamin B5, coconut oil, and loquat fruit extract, which reviewers mention smells amazing. On top of strengthening your hair and giving it a lustrous glow, this condition nourishes it without any potentially harmful parabens or sulfates, making it one of the most eco-conscious conditioners on the market.

Continuing about the unique formula blend within this duo, Federico says, "Pro vitamin B5 delivers intense hydration while coating each strand to add luster and shine. Lastly, Coconut Oil (an ingredient that I also recommend for dehydrated hair). This promoted scalp health but can also help to prevent splitting and breakage."

Federico suggests topping off your hair routine with this thickening spray, which adds a ton of volume to your locks. He says, "This combination of products will plump each individual strand (making the hair feel thicker, overall), while delivering root to tip strength." It's completely sulfate- and paraben-free, and you can use it on wet or dry hair to make it look thicker in a snap. The aloe leaf extract and honey help to lock in moisture and prevent frizzing, while the ginger root extract protects your hair from damage.

Just massage into the roots of your wet hair, style as usual, and step out with strong, healthy hair.

Izquierdo suggests adding this silky conditioner to your hair after shampooing for added thickness and volume.

Dawn Clemens, hairstylist, beauty blogger, and founder of LarweHair, suggests using this revitalizing scalp serum to help with thinning hair.

The invigorating blend of coffee extract and tea tree oil encourage hair growth, while amla, kahai seed, and other nutrients help to relieve dry scalp. It'll help leave you with luxe locks that only go stronger with time.

Clemes also suggests this scalp-stimulating shampoo, and she says, "This is the best option for people dealing with hair thinning."

It's also sulfate- and paraben-free, which can help prevent unwanted frizz.

Eve Cabanel, a beautician hairstylist from Organic Beauty Recipes, recommends using this biotin and collagen-infused shampoo. She calls it "a volume-creating powerhouse with an extra helping of vitamins and proteins to pump up fine strands." The included biotin — which is critical for healthy hair, skin, and nails — is paired up with collagen, which is full of nourishing amino acids. This winning combination helps your hair to grow back thicker and stronger, while the bamboo extract and hydrolyzed wheat protein seal in moisture and prevent damage to your hair while it's regenerating.

It's formulated with a blend of three natural ingredients — including palmetto berry, green tea extract, and caffeine — that have been proven effective at blocking DHT, a byproduct of testosterone that can cause hair thinning over time. And it's extremely easy to use. Just rub a small amount of this foam into your hair at the roots everyday to help new hair grow in thicker.

Elizabeth Mullans, M.D., a board-certified dermatologist at Uptown Dermatology, suggests adding these biotin-infused gummies help to strengthen your hair from the inside out. She says, "Take a multivitamin such as Vitafusion multivitamin every day because it’s good for overall health and contains biotin, which aids in the growth and health of skin, hair, and nails.” The daily serving contains a blend of biotin and vitamins C and E, all of which help your hair, skin, and nails to grow strong and healthy. Plus, they taste like raspberries. As always, it's best to speak with your doctor before adding a new supplement to your diet.

Dr. Sobel says brushing your hair when it's wet can lead to breakage — but if you must, you should use a Wet Brush to help absorb water from the shower. What makes these brushes so different are the extremely soft IntelliFlex bristles. These bristles cut smoothly through your hair — whether you're brushing it wet or dry — helping each strand to gently untangle and preventing further hair loss. Plus, you get two brushes in a pack, so you can always have one on hand.

William Gaunitz, WTS, certified trichologist and founder of Advanced Trichology, suggests using this high-potency vitamin D supplement to help prevent hair thinning. He says, "Vitamin D3 is critical for hair growth and immune function," and that it's "typically low" in people who are losing hair. This vitamin D supplement supports healthy hair and skin growth, and taking five drops per day is recommended. (However, it's best to talk with your doctor before adding this supplement to your diet.)

Gaunitz also recommends using this hair growth shampoo, which is infused "antifungal, antibacterial and pro-hair-growth herbs that keep the scalp clean and provide an optimal environment for hair regrowth," he says. Ingredients include biotin, saw palmetto, tea tree oil, and more DTH-blockers. This shampoo leaves your hair feeling fuller while helping stimulate follicles for even more growth.

Monica Davis, a professional hairstylist and founder of the MyStraightener blog, suggests using this luxe hair mask. Made with keravis protein and argan oil, it gets deep into every strand to revitalize your hair from root to edges, therefore helping to prevent thinning. This is a 2-ounce bottle — but if you like it enough, you can opt for the 16.9-ounce container.

Davis also recommends this volumizing hair tonic, which is enriched with organic aloe to help create fullness. This tonic is also infused with wheat amino acids to help strengthen your hair, while the essential oils leave behind a light, pleasant scent. To use, just spritz a bit onto your scalp or in your palms, then run your hands through your hair for instant lift.

Nunzio Saviano, salon owner and award-winning hairstylist, recommends using this professional-strength shampoo to help with hair thinning.

Each wash also helps to restore your hair's overall health, leaving it lustrous and strong.

Sophia Porter, celebrity hairstylist and licensed cosmetologist, recommends this protective treatment to help rejuvenate your scalp and healthy hair growth.

Plus, reviewers have mentioned that this shampoo lasts for quite a long time, so it'll be awhile before you need to invest in a new bottle.

McDavid also suggests this fiber spray, which can come in handy if you're trying to conceal hair thinning or hair loss. This advanced powder formula sprays onto your existing hair evenly, and the clump-proof "fibers" look just like real hair so it's completely unnoticeable. This spray also comes in a variety of colors so you can find the best match — and on top of that, it stays put until your next shampoo.

Many reviewers have mentioned that regular use of this oil helped their hair to appear fuller, healthier, and shinier in about a month.

Bergamy also recommends this leave-in elixir, which is made with a blend of keratin, biotin, and zinc to help your hair grow fuller. To use, just place a few drops in your palm and smooth it through your hair to instantly leave your locks voluminous and silky-soft. You can use it on wet or dry hair, and reviewers have also mentioned that this elixir smells heavenly.

Joe Rosenblatt, owner of Dr. Hempster, suggests using this anti-hair loss shampoo to help prevent hair thinning. It's made from five all-natural ingredients that promote overall hair and scalp health. First, there's hemp oil, which can help stimulate new hair growth.

Made especially for women, this minoxidil foam has been clinically proven to help regrow hair.

This exfoliating cream works like a charm on dry, itchy scalps. To use, apply in a grid-like pattern over your scalp, pop on some latex gloves, and rub into your scalp for five to six minutes. This innovative cream helps to gently and effectively remove old skin and buildup across your scalp for faster growth and healthier hair overall.

If you're stocked up on products, you might want to add a silk pillowcase to your bed set. These ones are made with smooth satin that's gentle on your hair to help prevent breakage. Dr. Sobel chimed in about silk pillowcases in general, and he said that they "allow the hair to slide around on your pillow, which can help with smooth hair. These materials will also not pull or damage your hair or hair follicles."

Not only do these spiral hair ties alleviate pressure at the scalp that you'd typically experience with standard elastic bands, but they also help prevent tangling and breakage (thanks to their spiral design). According to Shelly Aguirre, a stylist at Maxine Salon, no-pull hair ties in general can help with hair breakage. She says, "Scrunchies, satin pillowcases and no-pull hair ties are great for finer/thinner hair in general. Less friction helps prevent hair breakage, which any fine hair clients wants and needs."
