This is an interventional treatment trial for Excess Hair Growth focused on measuring Helos, Hair Removal, Hair Reduction
Eligibility Criteria
Inclusion Criteria:
- Subject is not pregnant and does not plan to become pregnant during their 16 month study period

- Subject is willing to have 5cm x 5cm square patches of reduced hair on all treatment areas for some time during and after the study period, perhaps even permanently
- Subject is willing to participate in the study
- Subject is willing to avoid sun exposure and tanning of the treatment areas for a time spanning two weeks before the first treatment to two weeks after the last treatments
- Subject has the ability to adhere to post treatment care requirements.
- Subject can commit to follow-up schedule
- Subject is willing to have photographs taken of the treated area which will be used de-identified in evaluations and may be used de-identified in presentations and/or publications
- Subject can read and comprehend English

- Subject has injury, scarring or infection in the treatment areas
- Subject has a tattoo in the treatment areas
- Subject is pregnant or is lactating or plans to become pregnant during their 16 month study period. Pregnancy will be assessed by question at screening
- Subject is not willing to have long term hair loss in the treated areas
- Subject is not willing to discontinue shaving treatment areas at least one week prior to treatment and follow-up visits
- Subject has an active electrical implant anywhere in the body, such as a pacemaker, an internal defibrillator, insulin pump, incontinence device, etc

- Subject is taking anticoagulation medication
- Subject has a known history of hypertrophic or keloid scars following skin injury
- Subject has known collagen vascular disease such as scleroderma, lupus, etc
- Subject is immunocompromised (including HIV infection or AIDS) or currently using immunosuppressive medications

- Subject had electrolysis treatment over the treatment areas
- Subject had any type of professional intense pulsed light (IPL), laser or RF hair removal in the treatment areas
- Subject has any other condition which in the physician's opinion would make it unsafe for the subject to be treated

Arms of the Study
Arm 1
Arm Type
Experimental
Arm Label
755nm alexandrite laser with bipolar RF
Arm Description
GentleTouch (Helos) combines 755nm alexandrite laser energy with bipolar RF energy.
Outcomes
Primary Outcome Measures
Average percentage of hair reduction by hair counts at baseline compared to 3 months after last treatment
The primary efficacy endpoint is to measure the average percentage of hair reduction at 3 months post last treatment computed over all subjects and all treatment sites. Hair reduction will be evaluated by counting the number of terminal hairs present in the 3 cm by 3 cm defined region by at least two independent blinded trained reviewers of photos taken at baseline and at the follow-up visits.
Secondary Outcome Measures
Average hair reduction for each anatomical site

5. Study Description
Brief Summary
The objective of this post marketing study is to further explore a variety of treatment parameters in order to optimize the optical (laser) and electrical (RF) treatments over the various skin types, when using a combination 755 nm alexandrite laser together with a bipolar RF energy system, for the purpose of hair reduction.
Detailed Description
The study device (Helos) combines 755nm alexandrite laser energy with bipolar RF energy. The laser can deliver 0.25 to 100 ms laser pulses at a maximum of 20 J/cm2. Bipolar RF energy will be delivered across the laser beam via two appropriately sized electrodes and spacing between the electrodes. Bipolar RF energy may be delivered at a maximum of 35 J operating at 1 MHz. Typical RF pulses will be of duration of between 100 and 300ms. Epidermal cooling is accomplished via contact with a cooled window.

Intervention Description
Four distinct areas on each selected anatomical area will be treated with different treatment parameters.
Primary Outcome Measure Information:
Title
Average percentage of hair reduction by hair counts at baseline compared to 3 months after last treatment
Description
The primary efficacy endpoint is to measure the average percentage of hair reduction at 3 months post last treatment computed over all subjects and all treatment sites. Hair reduction will be evaluated by counting the number of terminal hairs present in the 3 cm by 3 cm defined region by at least two independent blinded trained reviewers of photos taken at baseline and at the follow-up visits.
Time Frame
Baseline, 3 months after last treatment
Secondary Outcome Measure Information:
Title
Average hair reduction for each anatomical site
Time Frame
6-12 months after last treatment
Other Pre-specified Outcome Measures:
Title
Side Effects and Adverse Events
Description
Safety will be evaluated based on the incidence and severity of adverse events caused by the laser treatments
Time Frame
one year
Title
Histologic analysis of H&E stained tissue sections from biopsies
Description
Post-treatment biopsies may be taken at any time between the first treatment visit and the second treatment visit, prior to treatment.
Time Frame
day 1
Title
Numerical Response Scale for Rating Pain (NRS)
Description
To evaluate subject's assessment of comfort associated with treatments. Treatment related pain will be assessed immediately after treatment, the subject will be asked to define how much pain they felt from treatment by choosing a number from 0 to 10.
Time Frame
every 4-6 weeks up to 24 weeks
