How It Works

How It Works

Increased Blood Circulation:

  • Red light therapy improves microcirculation in the scalp, increasing blood flow to hair follicles.
  • This enhanced circulation delivers more oxygen and essential nutrients to the follicles, vital for healthy hair growth.

Nutrient Delivery

Essential Nutrients. Stronger Strands.

  • The improved blood flow ensures that hair follicles receive a steady supply of nutrients such as vitamins, minerals, and proteins.
  • These nutrients support the production of stronger hair strands and prevent hair thinning.

Cellular Regeneration

Regrow from the Root

  • The therapy supports the regeneration of damaged or inactive hair follicles, restoring their ability to produce hair.
  • By reducing inflammation in the scalp, red light therapy creates a healthier environment for hair growth.

Healthy Habits

Consistency and Long-Term Benefits:

  • Regular use of red light therapy can help maintain the health of hair follicles, preventing hair loss over time.
  • Users may notice gradual improvements in hair thickness, density, and overall scalp health with consistent treatment.

100% Medical Grade Laser Diodes

Capillus devices use laser-only technology, to penetrate down to the hair follicle, unlike LEDs, which disperse and do not penetrate to the same depth.

The Science Behind Capillus Red Light Therapy

Explanation:

Red light therapy involves the use of low-level lasers or LEDs to penetrate the scalp and stimulate hair follicles. The light energy is absorbed by the cells, enhancing cellular activity and promoting hair growth.

How It Works:

Red light increases blood circulation in the scalp, bringing more oxygen and nutrients to hair follicles, which in turn helps them grow stronger, thicker hair.

Load video:

The Difference Between Laser and LED Therapy

Why Lasers Matter:

Lasers offer concentrated, high-intensity light that can penetrate deeper into the scalp, directly targeting hair follicles.

The Misconception About LEDs:

While LEDs emit light, they do not have the power to penetrate deeply enough to stimulate hair growth effectively.

The Science Behind Red Light Therapy

Concept Overview:

  • Red light therapy, also known as low-level laser therapy (LLLT), is a non-invasive treatment that utilizes specific wavelengths of red light.
  • These wavelengths typically range from 630 to 660 nanometers, which are known to effectively penetrate the scalp.

Mechanism of Action:

  • The light energy emitted by medical-grade lasers is absorbed by cells in the scalp, particularly within the hair follicles.
  • This absorption triggers a series of biochemical reactions, known as photobiomodulation, which enhances cellular function.
  • The increased cellular activity boosts the production of ATP (adenosine triphosphate), the energy currency of cells, leading to improved cell function and repair.

Benefits for Hair Growth:

  • The enhanced cellular activity stimulates the hair follicles, encouraging the growth of new, healthy hair.
  • Red light therapy helps prolong the growth phase (anagen phase) of the hair cycle, resulting in thicker, fuller hair.

Combat Hair Thinning and Boost Volume

Regrowth and Volume

  • Red light therapy is scientifically designed to penetrate the scalp, targeting the hair follicles directly.
  • It stimulates the follicles, promoting the regrowth of hair strands, leading to increased hair density and volume.
  • Women experiencing diffuse thinning will notice fuller, thicker hair over time, restoring confidence in their appearance.

Hormonal Support

  • Ideal for women facing hair loss due to hormonal fluctuations, such as those occurring postpartum, during menopause, or due to other hormonal conditions like PCOS.
  • Red light therapy can help balance the scalp’s environment, making it more conducive to hair regrowth despite hormonal challenges.
  • By supporting hormonal health at the scalp level, the therapy aids in reducing hair shedding and maintaining healthy hair cycles.

Safe and Gentle

  • This non-invasive treatment is gentle on the scalp and suitable for all hair types and textures, from straight to curly, and everything in between.
  • Red light therapy does not involve harsh chemicals, making it a safe option for women with sensitive skin or those prone to allergic reactions.
  • It can be seamlessly integrated into daily routines without the need for special preparations or aftercare, providing an easy and stress-free solution for hair care.

Tackle Receding Hairlines and Balding

Stimulates Dormant Follicles

  • Red light therapy penetrates deep into the scalp, reactivating dormant or weakened hair follicles.
  • This process is particularly effective in areas prone to male pattern baldness, such as the hairline and crown.
  • By stimulating these dormant follicles, the therapy helps in regrowing hair in thinning areas, potentially reversing the early signs of balding.

Convenience

  • With just 6 minutes of daily use, red light therapy is designed to fit into even the busiest of schedules.
  • The short, time-efficient sessions allow men to easily incorporate the treatment into their daily routine, whether in the morning, during a lunch break, or before bed.
  • The hands-free operation of many red light therapy devices allows users to multitask, making it an ideal solution for those with active lifestyles.

Clinically Proven

  • Red light therapy is backed by clinical studies showing its effectiveness in treating male pattern baldness.
  • Users can expect visible improvements, such as a reduction in hair loss and an increase in hair thickness, typically within 12 weeks of consistent use.
  • The therapy’s non-surgical approach provides a less invasive alternative to hair transplants, with no downtime or recovery required.
