What they say
Bon ChargeRed Light Cap
No Reddit owner reports using the cap.
Bon Charge's owners on Reddit (r/redlighttherapy, r/Biohackers and r/SkincareAddiction, 2023 to 2026) write mostly about service: panels that arrived not working, slow email replies, store credit only on orders bought with a large code, and return shipping to Australia at their own cost.
None of it concerns a cap, so this reading sits a point lower.
KalaTherapy Hat
No Reddit post names the hat.
Kala's long r/redlighttherapy threads (January 2022, 191 comments; March 2023, 26 comments; March 2024, 42 comments) are dominated by shipping waits, refused or slow refunds and slow support, with a smaller group of Mini, Pro and mask owners reporting no problems; a 2026 commenter credits Kala with a good reputation for quality.
None of it concerns a hair cap, so this reading sits a point lower.

What they say
Bon ChargeRed Light Cap
No hands-on review of the cap is published; magazine pieces list it without a period of use.
Across Bon Charge's range, monetised editorial testers are mostly positive on build, comfort and ease of use and criticise the price: mindbodygreen, which publishes with Bon Charge's code, on six devices including the Mini and the wand, and Wareable, a market-wide affiliate, on the mask and the wand.
Light Therapy Insiders, a market-wide tester holding Bon Charge code ALEX, ranked the first-generation Max last of 17 panels on output in 2024.
None of that coverage is of a cap, so this reading sits a point lower.
KalaTherapy Hat
Marco Gentile's hat review, which carries Kala code MARCOGENTILE, relays testers' remarks and describes no sessions of his own, so it is not a pool.
Light Therapy Insiders (Alex Fergus), a market-wide tester with a Kala affiliate link, scored Kala's face mask 63 of 100 in July 2025 on a gifted unit, marking it down for coverage gaps, the cord and the return terms of the time, and found the Restore Wrap, also provided free, well built but low in output in September 2026.
Neither is a hair cap, so this reading sits a point lower.

The only cap video is a launch film made for Bon Charge.
Light Therapy Insiders (Alex Fergus), a market-wide tester holding Bon Charge code ALEX, found the first-generation Mini cheap but short on battery (2021) and would not recommend the first-generation Max (2022).
Vesna Kratka, who bought Bon Charge's face mask herself, used it most days for over a year, with a cord repair at 10 months (December 2025).
None of it concerns a cap, so this reading sits a point lower.
KalaTherapy Hat
The only hat video is Kala's own.
Red Light Therapy by Alex Fergus, a market-wide channel, scored Kala's face mask 63 of 100 in July 2025 (5,875 views) on a unit provided free, with Kala's affiliate link in the description, crediting its comfort, fit and price and faulting its coverage, its cord and the warranty terms of the time.
None of it concerns a hair cap, so this reading sits a point lower.

KalaTherapy Hat
Sam's Club lists the hat with no reviews.
Costco.com's Elite listing (item 2062084) has 3.9 stars from 11 native member reviews posted July to September 2026, with no syndication or incentive badge: owners praised the price against similar panels and Kala's phone support, and complained of no stand, a flimsy over-door hanger, a remote with no battery, poor instructions and a chemical smell on opening.
That coverage is of a panel, so this reading sits a point lower.
