Low-Level Laser Therapy (LLLT) is widely recognized as a safe and effective method for promoting hair growth. However, like any treatment, it may come with some side effects. The side effects of LLLT for hair growth are typically mild and temporary but understanding them in detail can help users make informed decisions and manage expectations.
What are the Side Effects of LLLT for Hair Growth?
Table of Contents
Low-Level laser Therapy devices such as laser caps, combs, headbands and helmets are usually safe and FDA-cleared. However, some users may experience temporary side effects especially at the early stages. Here are some of the potential side effects that you may experience:
1. Scalp Sensitivity or Redness
Users may notice mild redness, warmth, or sensitivity on the scalp after using LLLT devices. The increased blood flow stimulated by the laser light and the penetration of light energy into the scalp tissues can cause temporary inflammation. This side effect is common among first-time users and usually subsides within a few hours post-treatment.
How to Manage:
- Avoid pressing the device too tightly against the scalp.
- Reduce session duration or frequency if irritation persists.
- Apply a soothing aloe vera-based gel after use.
- If these effects persist, consult a dermatologist.
2. Itching or Tingling
An itchy or tingling sensation on the scalp during or after treatment may occur. The stimulation of dormant hair follicles and increased blood flow may cause this sensation, as the follicles begin to reactivate. This is a relatively common, especially during the initial weeks of use.
How to Manage:
- Ensure the scalp is clean and free of oils or residue before treatment.
- Moisturize the scalp with a lightweight, non-comedogenic lotion after the session.
- Avoid scratching, as it could lead to further irritation.
3. Increased Hair Shedding (Initial Phase)
During the first few weeks of LLLT use you may notice an increase in hair shedding. This is a normal and expected part of the hair growth cycle, where older hairs in the telogen phase are shed to make room for new growth. It is actually considered a positive sign that the treatment is working.
How to Manage:
- Continue using the device as directed, as this phase typically resolves within 1-2 months.
- Document progress with photos to track improvement.
Rare but Possible Side Effects
1. Headaches
Some users may report mild headaches after the treatment. This may be due to light sensitivity, tension from wearing the device, or prolonged exposure. This side effect is considered rare and affects only a small subset of users.
How to Manage:
- Reduce session time or use the device in a dimly lit room to minimize light sensitivity.
- Take breaks during longer sessions.
- Consult a healthcare provider if headaches persist.
- Follow manufacturer’s instructions for duration of use.
2. Allergic Reactions
Individuals with sensitive skin may react to certain materials, or adhesives.
How to Manage:
- Switch to hypoallergenic devices or products.
- Seek medical advice if symptoms persist.
How to Minimize Risks and Side Effects of LLLT for Hair Growth?
- Choose FDA-Cleared devices to ensure safety standards.
- Follow instructions and adhere to recommended session durations.
- Start gradually to gauge tolerance.
- Keep scalp clean to reduce irritation.
- Consult a professional if side effects persist.
