If you are frustrated by thinning hair but not ready for costly, painful surgery, you may have searched “noninvasive hair loss treatment” and discovered an overwhelming number of options. So, what are the most effective treatments for hair loss without a surgical procedure? In this article, we’ll explore the multitude of noninvasive solutions for hair loss available today.

Low-Level Laser Therapy (LLLT)

What is Low-Level Laser Therapy for hair loss? Also referred to as red light therapy, this painless, non invasive hair treatment utilizes low-intensity red light, which is FDA-approved to treat both male and female pattern baldness (androgenetic alopecia). It increases blood flow to the scalp and stimulates hair follicles, extending the hair growth phase, boosting cellular energy, and reducing inflammation to help inhibit hair loss.

LLLT treatments can be performed in-office with large red light panels or at-home with caps, helmets, headbands, handheld combs, or brushes. Laser therapy for hair loss requires consistent use two to three times weekly or every other day for 15-20 minutes over several months to see results.

The degree of improved hair thickness and density may vary based on the device used, frequency of use, and the degree of hair loss. (People with complete baldness won’t benefit, as there needs to be some functioning hair follicles to stimulate.) In-office treatments can cost anywhere from $50 to $150, whereas at-home devices may cost anywhere from $500 to $1,500.

Some words of caution:

• Mild scalp irritation, redness, and initial shedding may occur, but LLLT is mostly well-tolerated.
• People with psoriasis, lupus, cancer near the head and neck, photosensitive epilepsy, pregnancy, pacemakers, implanted electronics, and tattoos should consider refraining due to potential adverse effects.
• It is essential to protect your eyes from laser light exposure.

Platelet-Rich Plasma (PRP)

What is platelet-rich plasma (PRP) for hair loss? PRP refers to concentrated platelets in our blood plasma, which have the ability to promote tissue repair, wound healing, and blood flow, while reducing inflammation in the treated area. This treatment builds on your body's own healing capabilities, with the growth factors in the PRP helping stimulate and repair damaged and dormant hair follicles, fostering hair growth, density, and thicker hair. 

It involves extracting, then spinning your blood in a centrifuge to separate your PRP from the rest of your blood’s components, then injecting the PRP into the affected areas of your scalp. While less invasive than surgical hair replacement for alopecia, PRP injections can be painful and cause short-term redness, tenderness, bruising, swelling, or infection in the injected areas. It is often combined with micro needling, which can increase discomfort.

How many PRP treatments are needed for hair loss? Usually 3-6 treatments over several months, accompanied by maintenance sessions every 6 to 12 months. Unfortunately, the results of PRP are inconsistent, working better for people with early signs of hair loss as opposed to complete baldness.

How much do PRP injections for hair loss cost? The cost of PRP ranges from $500 to $1,500 per session, depending on the clinic’s location, the provider's experience, and the number of treatments required.

PRF, the newest form of PRP, contains fibrin in addition to a higher concentration of platelets and growth factors, for enhanced results and a higher price tag.

Microneedling for Hair Loss

What is microneedling for hair loss? Microneedling is a minimally invasive, professional hair loss treatment that utilizes tiny needles to create micro-punctures in the scalp, which trigger the body to send healing growth factors to the area, helping stimulate hair follicles.

It is also known as microchanneling, as the needles create tiny channels that enable the PRP, stem cells, or exosomes to penetrate deeply, thereby improving their efficacy. It can also help enhance the absorption of at-home topical treatments, boosting results. 

Microneedling is performed with a professional motorized device or pen in-clinic, or with a handheld dermaroller for hair thinning at home. Microneedling can be performed at different depths, with longer needles being more uncomfortable.

Scalp Micropigmentation (SMP)

Scalp micro pigmentation, also referred to as SMP, is a non-surgical method for creating the illusion of thicker hair. It is a cosmetic tattoo where a technician applies tiny dots of pigment onto the scalp, camouflaging thinning areas. This quick, noninvasive hair loss solution creates the appearance of denser hair follicles without invasive hair restoration treatments.

Two to six treatment sessions may be required to achieve the desired results, depending on the size of the area to be treated. Additional touch-up sessions may be needed over time to maintain the desired appearance.

SMP may not be suitable for individuals with psoriasis, eczema, or other skin conditions, with results varying according to the individual's skin tone, hair density, and the practitioner's skill. It may cause some potential side effects, including pain and discomfort during the procedure, mild and temporary redness, swelling, itching, crusting, or scabbing.  It can also cause rare but serious infections, allergic reactions, keloid scarring, color fading or discoloration, or uneven, blotchy results due to improper technique.

Topical and Oral Medications

What medications are there for hair loss? Until these newer therapies became available, topical and oral medications were the first choice for addressing hair loss.
Minoxidil, the most well-known topical hair loss treatment, is sold as Rogaine for women and Rogaine for men, available over-the-counter in foam and liquid form. It increases blood flow to the scalp, helping stimulate the hair follicles, encouraging growth, and slowing thinning.

Although effective for many types of hair loss, it requires consistent, long-term use to maintain results. It may cause scalp dryness, irritation, itching, scaling, flaking, stinging, redness, temporary hair shedding, unwanted hair growth elsewhere on the body, and changes in hair color or texture.

It is now available in gummy and pill forms, which are associated with additional risks – heart issues, fluid retention, more prevalent and pronounced body hair growth (compared to the topical form), headaches, nausea, and vomiting.

Topical minoxidil can be absorbed into the bloodstream, which may cause rare, more serious effects, including dizziness, lightheadedness, cardiovascular effects, weight gain due to fluid retention, allergic reactions, fatigue, and breathing issues. The risks are higher with the oral version.

Pregnant or breastfeeding women, individuals younger than 18 years old, and people with an irritated scalp, sunburn, or rash should refrain from using minoxidil. Due to these potential risks, those with medical conditions should consult a doctor before trying any of these hair loss treatments.

Finasteride, also sold as Propecia, is a prescription oral medication, primarily for men. It blocks dihydrotestosterone (DHT), a hormone that can shrink hair follicles, slowing hair loss and promoting regrowth.

Finasteride may cause diminished sex drive and sexual dysfunction in men, but these are rare side effects. Due to congenital disability risks, it is not prescribed to women of childbearing age. Women who are or may be pregnant should avoid touching crushed or broken tablets.

Dutasteride for hair loss is prescribed off-label to treat male pattern baldness. More effective than finasteride for DHT reduction, it also bears significantly more side effects, including a higher risk of high-grade prostate cancer. It is unsafe for women who are pregnant or trying to become pregnant.

Additional medications include antifungals like nizoral and DHT-blocking spironolactone or aldactone for women.

Natural Hair Loss Solutions

Are over-the-counter hair loss treatments effective, or should prescription options be considered?

Non-prescription, natural hair loss products with proven-effective ingredients are definitely worth trying before pursuing prescription medications that come with a host of potential side effects. In fact, some of the best hair loss products are available without a doctor’s visit.

A hair serum for thinning hair with effective natural ingredients is the ideal first line of hair loss defense. Choose formulas with moisturizing, antioxidant, antimicrobial, anti-inflammatory, and nourishing properties that support a healthy scalp environment. Castor oil, menthol, apigenin, oleanolic acid, biotinoyl tripeptide-1, and scalp-friendly amino acids help nurture the follicles and reduce visible shedding, promoting improved hair density and fullness. Together with a shampoo and conditioner for thinning hair, hair that looks fuller and stronger is achievable.

How long does it take to see results from a hair loss solution?

As hair undergoes 3 to 4 phases of hair growth, results require time and patience. Most treatments require consistent use for a minimum of 3 months to notice visible improvement, with full results taking up to a year or more.

How to approach noninvasive hair loss solutions more safely:

To determine if any of these options are right for you and minimize risks, consider these steps:

• Consult a dermatologist or hair loss specialist who can diagnose the reason(s) for your hair loss and confirm which course of treatment is appropriate.
• Talk to your doctor if you have any medical conditions or medications that may be contraindicated for various hair loss procedures.
