These cutting-edge gadgets can slow down the process of thinning and stimulate follicle production.

While there once was a time when visiting your dermatologist was the only way to treat thinning strands and signs of balding, the beauty industry has been stepping up its haircare game in recent years. Now there are a slew of products on the market that get to the root cause of the issue, including specially-formulated hair growth shampoos with effective ingredients like rosemary oil, hair-stimulating supplements, and even cool devices that uses the same technology in some of our favorite red light therapy masks.

"LED Red Light Therapy has been shown to particularly effective in treating androgenetic alopecia, which is a type of hair loss caused by a combination of genetic and hormonal factors," says Craig Ziering, D.O., F.A.A.D., dermatologist, hair transplant surgeon, and owner of Ziering Medical. "Unlike traditional hair growth treatments, red light therapy has no known side effects, making it a safer and more natural alternative."

Dr. Ziering also says there is evidence that low-level laser therapy (also referred to as cold laser therapy) and micro-needling can also work wonders in treating hair loss. The former method illuminates the hair follicles with monochromatic red laser light and uses a finely-tuned wavelength and intensity across a wide area of your scalp, says Dr. Ziering, while the latter uses teeny-tiny needles to cause minor skin injuries, which as a result, may help regenerate the health of the hair follicle.

It's important to note that while hair loss is not totally reversible, consistently using one of these at-home gadgets could at least slow down the process and stimulate new growth. Here, 6 of the best hair growth devices that money can buy.

This FDA-cleared helmut-like device harnesses the power of red light therapy to not only hasten regrowth, but to prevent future hair loss, reverse pattern balding, and receding hair lines by restrengthening the follicle. It's also very easy to use, super lightweight, and features built in speakers, so you can sit back, relax, and enjoy your favorite podcast.

Suggested Use: 10 minutes daily for 16 weeks

One reviewer writes: "Easy to use and size fit in perfectly, it’s so nice that given timer and Bluetooth connected automatically, it’s comfortable to wear and it’s weight not heavy, the light feeling warm and the material feel so durable."

The most inconspicuous hair growth device on the market, this cap allows you to grow on the go. It comes equipped with hidden red light therapy technology to prevent shedding, revitalize damaged strands, and rejuvenate the follicles for future growth. It's particularly effective for those dealing with genetic alopecia, but it's also suitable for menopause- and age-related hair loss.

Suggested Use: 6 minutes daily for 6 months

One Amazon shopper says: "It's been 2 months and only a small portion of the hairs fell out and the rest of them are growing like weeds. I can not believe how long they are getting. My receding hairline is way less noticeable and being a woman in my late 50s this is more important than you can ever imagine. If this is what can happen in just 2 months I am excited to see what is in store for me over the next 12 months."

The iRestore is another hands-free gadget that treats your hair and allows you to multi-task at the same time. The FDA-cleared hair loss treatment uses red light therapy to promote a fuller and denser mane, and it comes with an accompanying remote with a timer display that lets you press pause or restart whenever needed.

Suggested Use: Every other day for 25 minutes. Expect results in 3-6 months

One Amazon reviewer raves: "I am a 61-year-old woman, and my hair has been thinning for several years... I've been using the iRestore for almost two months... I'm happy to say that my hair is regrowing beautifully. I'm no longer self conscious about my hair style. I have lots of new baby hair coming in, and it's my natural dark color, not white like a lot of my hair is. I give most of the credit to the iRestore helmet; I've tried Rogaine for women in the past with little result, but this time around my hair is really responding."

This hair brush features nine medical-grade laser diodes that can be used to spot treat problematic areas or on the full scalp. According to clinical studies conducted by the brand, the device helps regrow hair with "an average hair count of 129 additional new hairs per sq. inch after six months." Plus, its compact size makes it travel friendly.

Suggested Use: 3 times a week for 11 minutes a session.

One Amazon reviewer writes: "My dermatologist recommended this product. He mentioned that I wouldn’t see hair growth right away, but the first signs it began working would be that my hair would stop falling out as much. He was right! I’ve only used it a few times, so far, and my hair falling has slowed substantially! I’m eager to see new hair growth now. One thing I recommend is that you use it every other day until you reach the maximum usage days to follow the three times a week as suggested in the directions."

If you're considering going down the micro-needling route, Bondi Boost's derma roller has 540 high strength medical grade stainless steel needles designed to be used across the scalp.

Suggested Use: Once a week on wet hair

One reviewer says: "This is a must have in my products and tool from Bondi! I can already tell a difference in my thinner spots on my head. I just started incorporating this product into my weekly hair care routine! I use it after i shower in my wet hair and so far so good. I'm excited to continue using it to see how it promotes hair growth."

When you want to achieve professional results at home, Dr. Ziering's cutting-edge hair growth device is your best bet. "The Ziering LaserCap stimulates inactive hair follicles using low-level laser therapy," Dr. Ziering explains. "It's a safe, all-natural, and painless hair regrowth treatment."

Suggested Use: 3 times a week for 30 minutes for the first 12 months

According to Dr. Ziering, there are many devices one can use to treat hair loss:

It all depends on the product you use. People who use Dr. Ziering's medical-grade cap usually notice a difference in their thinning areas within 60 days, while other FDA-cleared devices on the market deliver results starting in 3 months.
