Frequently Asked Questions

A laser cap is a wearable medical device that uses low-level laser therapy (LLLT) or red light therapy to stimulate hair follicles. The light energy penetrates the scalp and helps support healthier hair growth by increasing cellular activity in follicles.

Yes. FDA-cleared laser caps have been shown in clinical studies to improve hair density and thickness in both men and women with hair loss. Results vary, but many patients notice reduced shedding and gradual regrowth with consistent use.

Low-level laser therapy works by:

• Increasing blood flow to hair follicles
• Stimulating follicle cell metabolism
• Prolonging the hair growth (anagen) phase
• Reducing follicle inflammation

This helps revive weakened follicles rather than creating new ones.

Laser caps work best for:

• Male pattern hair loss (androgenetic alopecia)
• Female pattern hair loss
• Early to moderate thinning
• 
  

They are less effective for completely bald areas or hair loss caused by scarring conditions.

Most users see results in 3–6 months, with continued improvement up to 12 months. Reduced shedding may occur earlier. Consistency is critical—skipping treatments can reduce effectiveness.

Most laser caps are used 3–4 times per week for 20–30 minutes per session. Always follow the manufacturer’s instructions or physician guidance.

Yes. FDA-cleared laser caps are considered safe and non-invasive. They do not generate heat or damage the scalp. Side effects are rare and typically mild, such as temporary scalp tingling or warmth.

Absolutely. Laser caps are effective for female pattern hair loss, postpartum shedding, and age-related thinning. They are one of the few treatments suitable for women who cannot or prefer not to use medications.

Yes. Laser caps often work best when combined with:

• Topical treatments (e.g., minoxidil)
• Oral medications (when appropriate)
• Nutritional support
• Proper scalp care
• PRP

Combination therapy addresses multiple causes of hair thinning.

Laser caps work differently, not better or worse.

• Laser caps stimulate follicles physically
• Medications work hormonally or chemically
• 
  

Many patients use laser therapy as part of a multi-modal hair restoration plan.

Some users experience mild initial shedding as dormant hairs are pushed out to make way for healthier growth. This is temporary and usually resolves within a few weeks.

Medical-grade laser caps typically offer:

• Higher quality diodes
• Clinically validated wavelengths (around 650 nm)
• Consistent power output
• FDA clearance

Laser caps are FDA-cleared, not FDA-approved. FDA clearance means the device has been shown to be safe and substantially equivalent to other legally marketed devices.  Medical devices are "cleared" by the FDA since they are not medications to be "approved".

Hair loss is typically a chronic condition. If treatment stops, results may gradually reverse. Most users continue maintenance sessions to preserve gains.

For many patients, yes. Laser caps offer a drug-free, non-surgical option with long-term usability. Over time, ownership can be more cost-effective than ongoing treatments or procedures.

It’s recommended—especially if you have:

• Sudden or unexplained hair loss
• Scalp conditions
• Hormonal disorders

A medical evaluation helps ensure the treatment plan matches the cause of hair loss.

The light energy in laser caps helps revive the stem cells in your hair follicles.  Research shows they are effective, but patience is key.  It takes up to a year to see marked results.  When combined with a comprehensive program including prescription meds and supplements, they can have a yet stronger impact on hair growth.  Not all laser caps are the same.  We use the Capillus and GroWell caps, since they are very easy to use as part of a complete program.  They are fashionable, and it only takes minutes a day. Moreover, clinical research shows it works!
