Hairloss and Hair Rejuvenation: What You Need To Know
What Is Androgenic Alopecia?
Androgenic alopecia—also known as male or female pattern hair loss—is a common, gradual condition caused by genetics and sensitivity to the hormone dihydrotestosterone (DHT). It typically begins in adulthood and is more likely if family members are affected. In men, hair loss starts at the temples or crown and may progress to baldness.
Women experience diffuse thinning, especially at the crown, but rarely become fully bald. DHT shrinks hair follicles, producing thinner, shorter hairs that eventually stop growing. Treatments include minoxidil, finasteride (for men), spironolactone (for women), hair transplants, platelet-rich plasma, and low-level laser therapy. Effectiveness varies, so consulting a doctor is recommended.

Hair Growth Cycle
Hair grows in three main stages: anagen (growth), catagen (transition), and telogen (resting and shedding). Normally, most hairs are in the anagen phase, which lasts several years. In hair loss conditions like androgenic alopecia, the growth phase shortens and more hairs enter the resting phase, leading to thinner hair and increased shedding. Understanding these cycle changes helps doctors diagnose and treat hair loss.
Low-level laser therapy
LLLT for hair loss is an FDA-certified, safe, and effective treatment for pattern hair loss in both men and women. A 2014 randomized controlled trial published in The American Journal of Clinical Dermatology found that participants using laser combs had significantly increased hair density compared to those using a placebo1. Other clinical studies have shown that LLLT increases hair density, thickness, and strength, while reducing shedding2. It works by stimulating dormant hair follicles and prolonging the hair growth phase. LLLT can be used alone or alongside treatments like minoxidil or finasteride for enhanced results.

How it works
Low-level laser therapy (LLLT) uses true laser diodes that emit monochromatic red light to stimulate hair follicles. This FDA-cleared treatment promotes hair regrowth in men and women by triggering photobiomodulation. This process activates mitochondrial enzymes to boost cellular energy and improve follicle viability. Miniaturized hair follicles absorb the red light, encouraging them to remain in the anagen (growth) phase.
Can Laser Therapy Cause Damage?
While generally safe, some users may experience temporary shedding, scalp dryness, itching, or redness. You may feel some heat to the scalp when undergoing therapy. However, permanent damage is extremely rare, though direct eye exposure to the lasers should be avoided.
In Addition to Low Level Laser Therapy, What Therapies Can Be Used To Help With Hair Loss?
Hair transplants are the most robust treatment for restoring hair, but they don’t prevent future hair loss in areas that weren't treated. That’s why it’s important to use other treatments to help keep both transplanted and existing hair healthy.
Finasteride (Propecia) is a pill that helps keep hair in the growing phase by blocking a hormone called DHT. It can take a few months to see results. It’s helpful for keeping the hair you already have, but it may cause side effects like trouble with erections, breast growth, or feeling sad. You need a doctor’s prescription to get it. There are also sprays and creams with finasteride, and the results look promising.
Minoxidil (Rogaine) is a treatment you put directly on your scalp. It can help keep your hair healthy and can work well with finasteride. Some people notice more hair shedding at first, but that usually goes away. It can sometimes cause scalp irritation. There’s also an oral version, but it may affect your blood pressure and cause other side effects.
Platelet-Rich Plasma (PRP) is a treatment where doctors use your own blood to help your hair grow. It can work, but it’s expensive, requires repeated regular treatments, and can be painful.
Exosome therapy is another option, but it’s very expensive and not yet approved by the FDA. Scientists are still studying if it’s safe and effective.
Other pills like oral minoxidil or spironolactone might help too, but they can have serious side effects and must be prescribed by a doctor.
In general, most patients require one or several treatments to maintain your hair. Most specialists that deal with hair loss will recommend a combination of therapies.
Frequently Asked Questions
How Can I Buy a Lasercap?

Is LaserCap Suitable for Both Men and Women?
Yes. LaserCap is effective in treating pattern hair loss in both men and women.
What Are the Side Effects of LaserCap?
LaserCap is an FDA-cleared medical device proven to be safe and well-tolerated by most people. A small portion of LaserCap users may experience slight itchiness of the scalp or mild headache while receiving low-level laser therapy. These side effects are temporary and would only occur during treatment.
Can I Use LaserCap With Other Hair Loss Treatments?
Most dermatologists and hair treatment experts recommend using a combination of therapies because they often work better together. Studies have shown that using multiple treatments can help reduce inflammation, speed up healing, and improve the survival of hair grafts after a transplant. For example, a 2014 study showed better healing after hair transplant surgery, and a systematic review from 2025 found that laser therapy worked well when combined with minoxidil. When used with finasteride, laser therapy also helped regrow hair in the top and middle of the scalp by waking up the sleeping hair follicles and supporting finasteride’s effect of lowering DHT.

Can I Maintain My Hair After Stopping LaserCap?
The LaserCap is proven safe for long-term use. Like other non-surgical hair loss treatments, your results will decline over time if you stop using our LLLT device.
Is LaserCap Effective for All Hair Loss Patients?
Because it’s a non-surgical hair loss treatment, LaserCap results can vary between patients. Low-level laser therapy can reverse hair loss in some people. For others, LLLT devices can slow or stop the progression of hair loss. If you have advanced balding, LaserCap alone will likely not help you achieve meaningful results.
How Many Different Types of LaserCaps Do You Offer?
We offer three different LaserCap options: LaserCap SD, LaserCap HD, and LaserCap HD+. These hair growth hats differ in price, energy dosage, and area of coverage. Visit our Get Started page to learn more about the different LaserCap options.
