Non-Ablative Laser to Treat Scarring Alopecia With Hair Follicle Gene Expression Analysis

December 9, 2025 updated by: Montefiore Medical Center

1470 nm Non-Ablative Laser for the Treatment of Scarring Alopecia: A Clinical and Mechanistic Study

The goal of this clinical trial is to evaluate the effectiveness of a non-ablative 1470 nm laser in treating scarring alopecia in adults. The study will also investigate the biochemical molecular pathways involved in laser therapy by analyzing hair follicle gene expression before and after laser treatment.

The main questions it aims to answer are:

  1. Does a non-ablative laser work to effectively treat scarring alopecia?
  2. What molecular pathways are associated with the laser's effects on hair follicles in scarring alopecia?

Participants with scarring alopecia will:

  • Receive 3 laser treatments, spaced 1 month apart (Month 1, Month 2, Month 3), and attend 5 follow-up visits (Month 4, Month 6, Month 9, Month 12 and Month 15)
  • Have hair follicle samples collected via hair plucking of 10 hairs prior to the start and 1-month post-completion of laser treatments for gene expression analysis of inflammatory and fibrosis pathways implicated in scarring alopecia. Hair samples will be de-identified and kept anonymous.
  • Fill out questionnaires at each visit
  • Keep a diary of any side effects from laser treatments

Detailed Description

This is a prospective, single-center, open-label, baseline-controlled study evaluating the molecular pathways of the effects of a non-ablative 1470 nm laser for the treatment of scarring alopecia. 5 treatment-naive (or at least 1 year since last hair loss medical treatment) participants with prior biopsy-proven or clinically diagnosed scarring alopecia will be enrolled into the study. Hair follicle samples will be obtained via hair plucking prior to the first laser treatment (Month 1) and 1-month post-completion of the laser treatments (Month 4). Each subject will receive 3 laser treatments, spaced 1 month apart, and 5 follow-up visits, planned for Month 4, Month 6, Month 9, Month 12 and Month 15. Measurement outcomes will be compared to baseline.

For this study, the investigators will use the non-ablative Sciton HALO ® laser (1470nm). The non-ablative fractionated treatments with minimal downtime provide synergistic benefit of minimizing tissue damage while improving treatment tolerance and efficiency. The laser works by creating micro-channels in the dermis of the pilosebaceous unit, while leaving bridges of untouched tissue for improved permeability, faster healing, and enhanced delivery of topical treatments. The laser creates controlled zones of coagulation within the dermis. The parameters of the laser will be set according to optimal operation protocol and in accordance with guidelines set forth by Sciton and standard of care. Each laser treatment will take approximately 10 to 15 minutes per subject. Pre-treatment procedure will consist of the application of topical anesthetic then cleaning of the affected area of the scalp with antiseptic, either 70% ethanol or 3% hydrogen peroxide. Post-treatment care will follow standard of care. The U.S. Food and Drug Administration (FDA) has cleared the 1470 nm laser for dermatologic purposes. This study will use the laser off-label for the treatment of alopecia. This laser has been approved for the treatment of skin resurfacing; however, research on the use of this laser in alopecia is lacking.

The investigator team plans to define the molecular mechanisms involved in laser treatment of scarring alopecia. Using a non-invasive method of hair plucking, we will evaluate the hair follicle gene expression of inflammatory and fibrosis pathways in participants with scarring alopecia prior to treatment. Changes in gene expression through gene expression analysis of hair follicles at 1-month post-laser treatment completion will also be identified.

The follow up phase will consist of clinical assessments including before and after photographs graded by blinded observers and hair density evaluation using the Canfield HairMetrix ® device. Subjects are instructed to inform clinical staff after the treatment if any adverse events are experienced and will complete patient questionnaires, pain scores, and self-assessments of hair growth.

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in Dermatology Life Quality Index
Time Frame: From Baseline/Month 1 to Month 15
The participant will answer a series of 10 questions to measure how much their scarring alopecia has affected their life over the past week. It uses a 10-question self-administered questionnaire where each question is scored from 0 to 3, with a total score ranging from 0 to 30. The change from baseline/Month 1 to the end of the study (Month 15) will be summarized. Positive scores will be indicative of greater impact on the quality of life and negative scores will be indicative of reduced impact on the quality of life.
From Baseline/Month 1 to Month 15
Subject Satisfaction Questionnaire
Time Frame: Month 2, Month 3, Month 4, Month 6, Month 9, Month 12, Month 15

Comparing baseline photos and current photos of the scalp, the participant will answer the following questions:

1. Please choose the option that best represents the change in how your hair looks OVERALL in the area treated? 2. Please choose the option that best represents the change in your hair THICKNESS in the area treated? 3. Please choose the option that best represents the change in your hair SHEDDING/LOSS in the area treated? 4. Please choose the option that best represents the change in your hair DARKNESS in the area treated.

The options will be: -3 = Greatly worsened -2 = Moderately worsened -1 = Slightly worsened 0 = No change 1 = Slightly improved 2 = Moderately improved 3 = Greatly improved.

The average values will be reported for each specified point in time for each of the 4 parameters (overall, thickness, shedding/loss, and darkness). Only the first 4 questions of the subject satisfaction questionnaire (as specified above) are considered relevant to the outcome.

Other Outcome Measures

Outcome Measure
Measure Description
Time Frame
Hair follicle inflammatory and fibrosis pathway gene expression analysis
Time Frame: Hair plucking to obtain hair follicle samples will be performed Month 1 (prior to the start of laser treatments) and Month 4 (1-month post completion of laser treatments)
Subjects will undergo hair plucking twice-once prior to treatment and once more at the 1-month follow-up of the study. Ten hairs will be plucked from scalp and placed immediately into a buffer solution in a de-identified tube. The procedure will take three minutes and will have no lasting side effects. Ribonucleic acid (RNA) will then be extracted, reverse-transcribed to complementary DNA (cDNA), and sequenced. Bioinformatic analysis will be done using Kallisto and DESeq2 software median-of-ratios method. A single unit of measurement (eg., log₂ fold-change or normalized counts) will be used to report all genes of interest, mainly inflammatory and fibrosis pathways implicated in scarring alopecia (eg. -TGF-β1, NLRP3, IL-1β, IL-18, COL1A1, COL3A1, CTGF, CCL2, CCL21, CXCL6).
Hair plucking to obtain hair follicle samples will be performed Month 1 (prior to the start of laser treatments) and Month 4 (1-month post completion of laser treatments)
