ErthSkin London Advanced Brush Review: A New Contender in Laser Hair Growth

In the growing market of laser hair growth devices, the ErthSkin London Advanced Brush stakes a notable claim. This brush is designed specifically for hair regrowth and thickening at home, targeting users who want a non-invasive, manageable solution. Built with LED technology and using a laser-based approach, it offers a practical, scientifically supported tool for combating hair thinning. On paper, this device stands out for its moderately high total optical power combined with a user-friendly brush form factor, which promises an effective yet comfortable treatment experience.

Specs & Features Explained

The ErthSkin London Advanced Brush carries several specifications that inform its usability and effectiveness. Most notably, it uses continuous laser light output at a precise 650nm wavelength, which is widely recognized for stimulating hair follicles through photobiomodulation. With a total optical power of 150mW spread across 10 laser diodes, it provides a balanced medium-density emitter arrangement that targets hairline, crown, and temples efficiently. According to specs, each laser diode outputs about 5mW coherent laser light, which is ideal for depth penetration while maintaining safety in a Class 3R laser power classification. The battery life of 90 minutes per charge enables multiple treatment sessions before requiring a recharge via USB-C, a modern and convenient charging standard. However, the device lacks cordless operation, so treatments always require a power connection. The device's dimensions are compact and lightweight at only 0.22 pounds with a height of 7 inches, making it easy to maneuver during treatments. The brush's adjustable fit allows it to accommodate various head sizes comfortably, although it does not incorporate pressure distribution features, which could affect comfort over longer sessions.

User Experience & Performance (Based on Specs)

Design & Build

The brush's physical design leans heavily towards portability and simplicity. Constructed from a mix of plastic and aluminum alloy, its exterior promises durability without excess weight. The silicone liner material adds a degree of comfort. It ensures it sits well against the scalp, compatible with a broad range of hairstyles, including short, long, curly hair, and even extensions. Users who wear glasses will appreciate that the brush is reportedly compatible with eyewear usage during sessions, a thoughtful ergonomic touch. On the flip side, the absence of ventilation or cooling features means that while heat perception remains low during use, long sessions could potentially cause discomfort in warmer environments.

Performance

According to its optical specs, this brush should deliver consistent and focused laser therapy. The 95% treatment consistency score suggests the device reliably emits laser light evenly, enhancing the potential effectiveness of each session. The recommended protocol is a 20-minute session repeated up to three times weekly, with visible results expected in approximately 12 weeks if users adhere closely to the regimen; a timeline corroborated by cited published studies. The device requires manual session timing; it doesn't have an auto timer or auto shut-off, so users must manage their treatment duration.

Safety & Compatibility

ErthSkin has adhered to crucial safety standards, including IEC 60601-1 and RoHS electrical certifications, along with EMC certifications like FCC and CE. The device is classified as a Class II medical device, but notably, it lacks FDA clearance, which may be a consideration for some users. Eye protection is not required, simplifying user experience, and the brush offers compatibility across all skin phototypes (I through VI). Additionally, it is safe for use during pregnancy and shows no contraindications according to the data. This solid safety profile supports its use as a home device with minimal risks.

Additional Features

Beyond its core functionality, the brush does not integrate Bluetooth or app tracking but does include audio beeps that assist users during operation. Though this is basic, the absence of session memory, reposition alerts, or LED indicators to communicate treatment status could limit ease of use for some consumers. The device operates entirely offline, refraining from data collection, which may appeal to privacy-conscious users.

Pros & Cons

Pros

• Strong total optical power of 150mW with coherent laser technology
• Comfortable brush form with adjustable fit and silicone liner
• Comprehensive safety certifications and broad skin phototype compatibility
• Convenient USB-C charging with 90 minutes of battery life

Cons

• No cordless operation; must always be plugged in during use
• Lacks advanced features such as auto shut-off, session reminders, or app connectivity
• Not FDA cleared, which may affect perceived credibility for some users
• No additional accessories like travel case, comb attachments, or cleaning tools included

Price & Value For Money

Priced at $46.21 at Superdrug, the ErthSkin London Advanced Brush is competitively positioned in the entry to mid-range sector of laser hair treatment devices. Given its 1-year warranty and battery type (Li-Ion) supporting decent charging longevity, the pricing feels justified for those seeking an affordable at-home option. The device's combination of a solid power output and safety certifications means users are getting a credible, thoughtfully engineered product without the premium price tag usually associated with medical-grade laser devices. That said, users expecting smart features or FDA clearance might find better value in higher-priced alternatives.

Quick Take

In short, the ErthSkin London Advanced Brush offers effective laser technology in a lightweight, ergonomic package that fits a broad range of users. Based on the numbers, the 650nm continuous-wave laser and the battery life make it a good choice for consistent home use. However, the lack of smart conveniences and regulatory clearances could be a deciding factor depending on personal preferences.

Closing Recommendation

This device may be ideal for users who want a straightforward and reliable laser hair treatment brush that balances power and portability without steep costs or complexity. It appears to perform best for those comfortable managing manual sessions who value safety standards and well-documented wavelength efficacy. It doesn't rely on flashy tech, but it provides a strong foundation for credible hair regrowth based on measurable engineering data.

Verdict

Rating: Based on the specifications and overall feature set, we believe ErthSkin London Advanced Brush deserves 4.1 out of 5.

• Winner Feature => High total optical power with coherent laser diodes ensures effective photobiomodulation.
