12 Hairstylists Reveal Their Favorite Products For Treating Thinning Hair

"These products in the Bosley BosDefense Kit for Color-Treated Hair ($40) are affordable and they work. I especially love that Bosley has different products per hair type, including ones specifically formulated for color-treated hair. They really understand and address visibly thinning hair while still remembering to address the needs of the hair itself (whether colored or not)." — Gabriel Samra, celebrity hairstylist

"The Kérastase Densifique Bodifying Mousse ($37) instantly transforms the hair fibers. Thickness, from roots to ends, is like added on and yet the fiber maintains a supple feel. Advanced treatment mousse for instant density without weight. Gives immediate improvement in hair's texture, shine, and suppleness. Adds body without weight." — Moses, stylist and founder of Hair by Moses

"I have recommended Nutrafol Hair Supplements ($79) to my clients and the feedback has been exceptional. After only two to three months of use, they have reported dramatically noticeable results. Their thinning/balding areas have begun to fill in, their overall density has dramatically improved, and as a result, the stress associated with losing hair has subsided." — Sascha Breuer, celebrity hairstylist

"The Phyto Phytolium 4 Densifying Scalp Treatment ($69) has been my favorite treatment for clients that have thinning hair. It uses plant- and fruit-based oils and extracts to replenish locks and stimulate healthy hair growth, along with active ingredients that create micro circulation in the scalp, strengthening the hair bulbs. You can maximize your results by using it three times a week for three months." — Xavier Velasquez, stylist at the Serge Normant at John Frieda Salon in New York

"Shu Uemura Volume Maker Hair Volumizing Powder ($48) is my go-to when I want my hair to feel thicker or when clients have thinning hair and want instant texture, body, and all-over lift. Just sprinkle and work into strands for instant volume and hold (hair will feel thicker and stand up or stay wherever you put it). It also works as a great back-combing base for a higher 'do, and absorbs excess oils so you look and feel fresh." — Jill Engelsen, senior stylist at Butterfly Studio Salon

"Toppik Hair Building Fibers ($47) gives the instant appearance of a thick, full head of hair. These fibers are made from natural keratin of the highest grade (the same type of protein found in real hair). They have a strong natural static charge that creates a magnetic effect, tightly binding the building fibers to even the finest strands of human hair. The results have changed the lives of millions of women and men, from those struggling with fine or thinning hair to those with alopecia or undergoing chemotherapy." — Deycke Heidorn, hairstylist

"Commonly used to mask grays, Color Wow Root Cover Up ($35) is a great quick fix for a big night out, whether you're walking a red carpet or attending a wedding. You can use the smaller end of the application brush around your temples or around your part line where hair seems less dense. This will instantly fill in your hair, leaving you looking camera ready from every angle." — Velasquez

"One of my clients brought these SnobGirls Prestocure Bio-Serum Capsules ($17) to my attention and now I recommend them on the daily! I've seen them work miracles on thinning and brittle hair. Massage the solution from one capsule into freshly washed hair (from roots to ends), then blow-dry hair and style as usual. I've watched this product take clients from a fine and broken hairline to full and supple hair in just a couple weeks." — Velasquez

"I recommend the Pura d'or Hair Thinning Therapy Shampoo ($25) and Conditioner ($15) to all of my clients (who are mostly female). If they begin using the Pura d'or Hair Loss Prevention Therapy System soon after my suggestion, I see results by their next color or cut visit, which can be as quick as three weeks. The system includes argan oil (for nourishing and strengthening), biotin, and caffeine extract (great for stimulating your scalp), and DHT blockers (essential for reducing hair loss as DHT is a huge enemy of your hair follicles)." — Cisco Reynoso, hairstylist at Salon Vivace in Torrance, CA

"This is a serious game changer. One of my clients (with some of the healthiest long hair I've ever seen) turned me on to Great Lakes Gelatin Collagen Hydrolysate ($25) and, after trying on my own hair and seeing results in as soon as one month, I now swear by it. I add two tablespoons of this magic powder to my morning tea or coffee and it completely dissolves and is tasteless. I've also recommended this to several other clients — the results on their hair (along with skin and nails) have been overwhelmingly positive." — Tina Malhotra, stylist at L'Appartement NYC

"Great hair begins with scalp health. When hair is thinning or there is significant loss, I've noticed that you'll have the best results if you fix the problem at the root. The Aveda Invati Scalp Revitalizer ($63) (from Aveda's three-part Invati system) prevents hair loss/fallout and increases hair thickness overall. I have seen amazing improvements in just two weeks with clients who have had thinning hair and use the spray regularly (applying to roots morning and night)." — Malhotra

"I have a client who started using SugarBearHair Vitamins ($30) only a month ago. Her hair has already grown about three inches so I highly recommend!" — Jennifer Matos, stylist at the Rita Hazan Salon in New York

"Oribe Maximista Thickening Spray ($39) is my go-to thickening spray for blow-drying fine hair, as it always adds thickness and fullness to hair without leaving behind any product residue. The key is to air-dry hair a little bit, then spray (about eight inches away from the hair). This will help you avoid overapplying the product. Focus at spraying at the root!" — Matos

"O&M Atonic Thickening Spritz ($30) encourages volume and is formulated with lilly pilly, a plant that serves as a collagen in the hair. Aloe vera adds a natural shine without weighing the hair down." — Jessica Heckman, hairstylist and owner of The Beautiful Co. in Greenville, SC

"Viviscal Extra Strength Hair Growth Supplement ($50) is a pill you can take to help stop hair loss and expedite regrowth. You must be vigilant with it and take for a few months to start seeing results, but it does work." — Tommy Buckett, consulting celebrity stylist for Garnier

"A new client started using the Harklinikken Liquid Hair Growth Extract ($88) and saw instant results. It's a serum you put on your scalp before bed and I can't begin to grasp all the science that it goes into it, but I do know it's amazing and works. I believe you need to consult someone (either online or if getting from an office). I want to try this out myself!" — Buckett

"The Vitalfan Dietary Supplements For Thinning Hair ($42) work by stimulating hair circulation with bitter orange extract. Pumpkin seed oil and vitamins B6, A, and E, along with watercress extract and high-grade biotin, help to regulate oil production and encourage healthy hair growth." — Michelle Schwartz, stylist at the B2V Salon in West Hollywood
