research Growth Inhibition and Transient Temperature Measurement of Laser-Irradiated Hair Fibers and Follicles

January 2000 in “Optics Letters”

This study found that the maximum infrared temperature of laser-irradiated hair depends on melanin type, with eumelanin-rich hair reaching higher temperatures than pheomelanin-containing hair.

Measuring Changes in Chemistry, Composition, and Molecular Structure Within Hair Fibers by Infrared and Raman Spectroscopic Imaging

research Measuring changes in chemistry, composition, and molecular structure within hair fibers by infrared and Raman spectroscopic imaging

42 citations , January 2011 in “Journal of Biomedical Optics”

This study demonstrates that spatially resolved IR and Raman imaging can effectively reveal the molecular structure and composition of untreated human hair, providing insights into its chemistry and structural integrity.

research High spatial resolution study of human skin using synchrotron infrared microscopy: application to the penetration of external agents

1 citations , November 2004 in “International Journal of Cosmetic Science”

In this study, synchrotron-powered infrared microscopy revealed that hair follicles are a favored penetration pathway for cyanophenol and ethylhexyl methoxycinnamate in human skin, without altering protein secondary structure.

research Phototherapy of androgenetic alopecia with low level narrow band 655-nm red light and 780-nm infrared light

2 citations , January 2007 in “Journal of The American Academy of Dermatology”

Red and infrared light therapy improves hair growth in balding patients.

research Treatment of hair loss with an LED device: the importance of the wave length

January 2026 in “American Journal of Medical and Clinical Research & Reviews”

The study discusses using red light therapy for hair regrowth, noting red light alone may aid non-inflammatory hair loss, while infrared-red light combination is necessary for conditions like alopecia areata.

community Predict if You'll Shed and Responding to Treatment: Ultrasound Imaging Technology

18 upvotes 1 year ago

Ultrasound imaging can predict hair shedding and assess hair growth stages by analyzing hair follicle characteristics. The conversation also discusses using ultrasound for personal hair analysis and mentions the potential use of infrared emission for hair treatment.

community 10 years of my hair journey (2015-Current). Looking for thoughts and feedback!

147 upvotes 1 year ago

The user has maintained their hair over 10 years using oral finasteride, oral and topical minoxidil, and other treatments like LLLT and ketoconazole. Despite starting hair loss at 17, they have largely preserved their hair, with some users suggesting a hair transplant for sparse areas.

community 5-Months Update: Minoxidil + Red Light Therapy + Lifestyle Changes

1023 upvotes 1 year ago

The user reported positive hair regrowth after 5 months using Minoxidil, red light therapy, and lifestyle changes, including dietary improvements and stress reduction. They chose natural supplements like saw palmetto and beta-sitosterol over pharmaceutical DHT inhibitors like finasteride.

community LLLT seems like it's at least a solid maintenance tool. Can also provide ok regrowth in AA and MPB. - Pubmed

17 upvotes 8 years ago

Low-Level Laser Therapy (LLLT) is seen as a safe and effective method for maintaining hair and promoting regrowth in androgenetic alopecia (AGA) and male pattern baldness (MPB), with devices like the HairMax LaserComb® and iRestore helmet being popular. Some users and professionals are skeptical about its long-term effectiveness and cost.

community My finasteride progress in a 6 month

1282 upvotes 8 months ago

Successful hair regrowth after six months using finasteride and topical minoxidil, with minimal side effects like anxiety. Finasteride was the main treatment, and minoxidil supported regrowth.
