11 Dermatologist-Recommended Hair Growth Treatments and Products

Try a PRP Treatment

Dr. Goldenberg explains that PRP (platelet-rich plasma) treatments "harvest the power of your own body to help hair grow and support hair health." During the procedure, blood is drawn and the PRP from the blood is injected into the area of the scalp with hair loss or thinning. Dr. Goldenberg notes that PRP does several things to improve hair loss. For one, it "contains growth factors that provide support for hair that's already present and for the hair follicles that are dormant and stimulates them to grow," says Dr. Goldenberg. "It also contains vascular growth factors. These increase circulation to the scalp providing hair with more nutrition and oxygen needed for growth."

"Because PRP contains a range of growth factors and proteins that speed up tissue repair, doctors will often use this therapy when hair loss is a result of androgenetic alopecia (pattern baldness), which causes hair follicles to shrink," adds Friese. PRP can be used as a stand-alone treatment or be combined with other hair loss treatments to help create lasting, healthy hair. For example, minoxidil can be used to complement PRP hair treatments and can be used long-term to sustain the results achieved from PRP, dermatologist, Michele Green, MD, says.

Minoxidil

Possibly the most famous hair loss treatment, Rogaine is successful at preventing hair loss and promoting new growth. "Rogaine is a topical solution or foam that blocks the type of testosterone that causes hair miniaturization—the process that causes androgenetic hair loss," says Dr. Goldenberg, who recommends it for women just once daily. Its active ingredient, minoxidil, is an FDA-approved topical treatment for male and female pattern hair loss, says hair transplant surgeon, Craig Ziering, DO, FAOCD. He also notes that it is available over-the-counter and does not require a prescription. Minoxidil comes both as a solution and foam base, which needs to be applied to the scalp at bedtime, explains Dr. Green.

Minoxidil is effective at treating certain types of alopecia, as research has found that minoxidil prevents the conversion of testosterone into dihydrotestosterone (DHT). DHT has been linked explicitly to hair loss in multiple studies, making the prevention of its creation paramount to preventing hair loss and generating new hair growth.

Vitamin B Complex Injections

Dr. Goldenberg explains that vitamin B complex injections can help to promote healthy hair. "Many cannot absorb vitamin B from their diet, so injections of vitamin B complex may be the best way to receive this vitamin," he notes. "Some patients with normal vitamin B levels can still benefit from these injections when it comes to hair loss and hair support."

Vitamin Supplements

Clinical trials suggest that certain supplements and vitamins—vitamins D and E, as well protein-rich collagen and plant-based compounds—can be effective in promoting hair growth, notes Dr. Ziering. Vitamin supplements Viviscal and Nutrafol have also been shown to support a healthy mane, adds Dr. Green. And according to Dr. Goldenberg. "Biotin, zinc, and copper supplementation can help to improve hair quality and growth." We're especially fond of Omi Hair Growth Peptides Capsules.

Thermadome

"Thermadome is a light device that one wears at least twice weekly for at least 20 minutes," says Dr. Goldenberg, who notes that some even wear it daily because you can't overdo it. "It stimulates hair to grow by shuttling nutrition and oxygen to the scalp."

"Low-level laser light has been used to regrow bone and tissue for years and the technology is now used for the stimulation of hair follicles and promotion of hair growth," Friese continues, "Thermadome is a kind of helmet or cap containing laser lights that aid in regrowing hair. The laser light targets the stem cells at the base of hair follicles, allowing the formation of a new photonic pathway that can restore hair to a healthy state."

Lasercap

The Lasercap is a prescription at-home FDA-approved device, which Dr. Green explains uses low light therapy to stimulate hair follicles. "The device is worn for 30 minutes, three times per week. I often recommend this device in combination with PRP treatments. The Lasercap is worn at home and is an excellent complement to any hair loss treatment," shares Dr. Green.

Laser therapies are still being studied to understand their impact on hair growth, but research suggests that improved cellular activity, reduced inflammation, and improved microcirculation may be involved. Dr. Ziering shares that the theory of laser treatment for hair loss is that the low-dose laser treatments invigorate circulation and stimulation that encourages hair follicles to grow hair. "Because the results of laser therapy are inconsistent, the conclusion of the medical community seems to be that it appears to work for some people, but not for others," says Dr. Ziering.

Proper Scalp Cleansing

It is important to keep your hair clean to encourage healthy growth. "Shampooing often is very important," says Friese, "Cleansing the hair follicles and keeping them free of oils, hair product build-up and free radicals will help create a healthy scalp environment for the hair to grow.

Scalp Massage

Scalp massage is another way to encourage hair growth, You could use a scalp massager or simply your fingers, and do double duty by taking extra time to massage your scalp while you shampoo.

A Well-Balanced Diet

Not getting the nutrients you need can lead to hair loss. "Poor nutrition can cause malabsorption as well as inflammation in the body, which can disrupt the growth cycle of the hair. Inflammation does not allow the cells to repair completely which results in a weakening of the cells. When this reparative process does not occur, it causes cell damage which results in hair loss," cautions Dr. Green.

Creating a better microbiome could help your hair return. Friese tells us that "we are discovering more about the importance of a healthy gut and how it affects hair growth. Foods high in proteins and healthy fats are key to a good diet. Staying away from processed foods and those high in sugar are also very important. I often recommend adding eggs (high in biotin that encourages hair growth), avocados, and nuts, which are easy and convenient options for attaining healthy fats," she adds.

Low-Stress Lifestyle

Keep in mind, that stress can also be a leading factor in hair loss. Working to create a low-stress lifestyle can be a powerful tool in promoting hair growth. Practice yoga, meditate, or enjoy a relaxing bath. Hydration levels also have a major impact on overall health and wellness, drink plenty of water.

Hair Transplantation or Hair Replacement Surgery

Depending on the severity and cause of your hair loss, your doctor may suggest a more permanent solution like hair transplantation or replacement surgery. Dr. Ziering explains that hair replacement surgery is a cosmetic procedure and includes such replacement procedures as micro-grafting, slit grafting, punch grafting, and scalp reduction. Some examples of these treatments are:

• Follicular Unit Excision and Extraction (FUE) is a surgical hair harvesting method used to obtain donor hair one graft at a time. 
• Microscopically Dissected Elliptical Excision (MDEE) (formally known as FUT) is a surgical hair restoration procedure in which hair is harvested from the donor zone on the back and sides of the head where your hair is genetically programmed as permanent hair, and then it is transplanted into the balding or thinning areas of your scalp.
  

Spironolactone

Spironolactone is an FDA-approved drug prescription medication that treats androgenetic alopecia in women by slowing down the production of male sex hormones (androgens), says Dr. Green. "Spironolactone is for females with hair loss due to hormonal imbalance it works by obstructing the androgen (male hormone receptors), which control the dihydrotestosterone (DHT) and testosterone levels, which can lead to different degrees of hair thinning or permanent hair loss," she explains.
