Prof. Graham Pierce, Ph.D.FDA-approved light therapy devices can effectively stimulate hair regrowth by reactivating dormant hair follicles. The red light emitted from these devices, operating at 660nm, will boost the cellular energy within the hair roots, allowing for proper blood flow and the delivery of nutrients to those thinning areas. Clients have reported visible thickening of their hair after using it daily.
Follicle Activation
- Process: 660nm light energizes follicle stem cells
- Effect: Shifts dormant follicles to growth phase
- Outcome: New hair shaft production begins
Blood Flow Enhancement
- Process: Increases nitric oxide production
- Effect: Boosts nutrient delivery to follicles
- Outcome: Thicker hair shafts and reduced shedding
Inflammation Reduction
- Process: Decreases inflammatory cytokines
- Effect: Creates optimal growth environment
- Outcome: Healthier scalp conditions
To achieve results, 25-minute sessions per day are a must. Position the FDA-cleared helmets directly against your scalp. Consistency over a period of 16 weeks is required to reactivate your hair growth cycles. I suggest taking photos every month to help track those subtle changes. Initially, shedding may decrease, but you won't see obvious thickening at this point.
Light therapy equals minoxidil results without the side effects. Clinical studies show similar regrowth percentages after 6 months. Many clients utilize both approaches commonly. Only medical products are used, not novelty items. Suggest brands with published clinical data.
The treatment is most effective for androgenetic alopecia and pattern baldness. Results vary for other autoimmune forms of hair loss. It's essential to speak with dermatologists first for a proper diagnosis. I consult with trichologists to develop integrated treatment plans. This addresses the underlying causes of the trouble with the light stimulus.
Ongoing maintenance will still be essential after initial regrowth occurs. Maintenance sessions can be reduced to three times a week, but they should never be eliminated. Hair has a cycle that requires support to maintain results. I have successfully treated clients in maintenance mode for over five years. This shows the sustainable benefits of light therapy.
