LLLT (Low-Level Laser Therapy)

LLLT (Low-Level Laser Therapy) capillary treatment is ideal for men and women who are in the early stage of baldness (androgenetic alopecia) or excessive hair loss due to:

• Scarring alopecia;
• Chemotherapy treatments;
• Prolonged illness;
• Medication;
• Menopause, postpartum, or discontinuation of contraceptives (women).

LLLT is also beneficial for patients who have undergone hair transplants or PRP (platelet-rich plasma) treatments, thanks to its regenerative effects that accelerate skin healing.

Note: It is not recommended during pregnancy or for patients taking immunosuppressants or with cancer.

Before treatment, it is important to follow some recommendations, such as:

• Stop taking or applying any photosensitive medication or product about 3 days before treatment;
• Avoid using hair styling products on the day of treatment (e.g., cream, hairspray, or gel).

We advise informing the doctor if you are taking any medication to confirm its compatibility with the treatment."

Yes. Low-level laser therapy has been used for the past 50 years to treat various clinical conditions, including hair loss. If performed correctly and following safety protocols, it is a safe and painless therapy.

Almost all treatments work better on hair follicles that are beginning a new growth cycle. Therefore, it is common to notice hair loss in the first 7-14 days. This is normal. Then, from the 2nd month, when most hair follicles have passed the initial phase of the cycle, the first results start to become noticeable.

At LHR Clinic, treatments are personalized, and the number of sessions is planned according to each case's specific condition. However, it is common for patients to achieve effective results with LLLT after 3 to 4 sessions, each lasting 15 to 30 minutes.

LLLT treatment promotes hair growth by stimulating existing hair follicles. Your hair will become stronger, thicker, and healthier, with reduced hair loss and increased growth of new hairs.

No. The only identified effect is temporary hair loss or telogen effluvium in the first few weeks after starting treatment. This effect is natural and expected to occur but gradually disappears with continued treatment.

LLLT capillary treatment is a non-invasive and painless procedure. The laser intensity is low, so patients will not experience any discomfort during or after treatment.

Yes. In the first few days, we recommend washing with gentle and delicate movements, reducing the shower pressure and avoiding direct contact with the scalp. After a few days, you can go back to washing your hair as usual.

LLLT is a hair restoration treatment that achieves better results when applied in the early stages of hair loss or partial hair loss. However, it is essential to determine the causes of the problem. Depending on your condition, it may be beneficial to combine other therapies, such as minoxidil.

Schedule your capillary evaluation consultation with Dr. Augusto Guerreiro, a specialist in capillary medicine, for a precise diagnosis and to find out the most suitable treatment for your particular case.
