THROW Hair Color Concealer: Putting Its Staying Power to the Test
Two to three weeks after a salon color service, gray hair at the roots, hairline and parting often starts to show again. THROW Hair Color Concealer is a foundation-type concealer designed to cover these areas temporarily — applied like makeup, and easily washed off with shampoo.
This article introduces the concealer, how it fits between salon color appointments, and a half-marathon wear test carried out by a b-ex staff member, as reported in the original BEAUTY GARAGE Japan feature.

About THROW Hair Color Concealer
THROW Hair Color Concealer is a foundation-type gray hair concealer for the gray hair that appears around the face and parting in the weeks after a color service. Just like foundation, it is applied to the areas of concern with the dedicated puff included in the compact case.
It blends in for a natural finish, does not feel sticky, and can be easily washed off with shampoo — making it convenient for busy mornings or quick outings.
- Type: Foundation-type hair color concealer
- Colors: Brown / Light Brown
- Content: 11g
- Included: Compact case with a dedicated puff
- Removal: Washes off with shampoo
Available in two shades, so the color can be matched to the client's hair color.
How It Fits Between Salon Color Appointments
Gray hair regrowth at the roots is often most noticeable in the weeks leading up to the next color appointment. THROW Hair Color Concealer is designed for this in-between period, offering a quick root touch-up that helps clients go comfortably until their next hair color service.
It can be suited to color-focused salons, community salons looking to strengthen their gray hair care offering, and salons with root coverage or gray hair maintenance menus.
b-ex Staff Wear Test: How Did It Hold Up During a Half Marathon?
As part of the original BGJP feature, a b-ex staff member set out to check whether THROW Hair Color Concealer would come off with sweat — by running the Toda Half Marathon in Japan with the concealer applied. As the staff member did not yet have gray hair, the concealer was applied directly to the hairline for the test.
2 km
The staff member reported light perspiration along the hairline, with no visible Light Brown colour in the sweat.
10 km
About an hour into the run, the staff member reported heavy sweating and hair that had lost its shape, but no visible loss of concealer.
At the Finish
The staff member finished in 1 hour 53 minutes. Even after a final sprint on the track left them flushed, the hairline still looked fine.
The staff member confidently answered the question, “Does THROW Hair Color Concealer really stay on when you sweat?”
“It didn’t come off at all!”
This was a single real-world wear test by one b-ex staff member, as reported in the original BGJP feature. Results can vary depending on the individual, the amount applied and the conditions of use.
Conclusion
With its stylish packaging, easy puff application and natural finish, THROW Hair Color Concealer is a salon retail item that stylists can recommend between color services. Offered as a home-maintenance option for root touch-ups, it can help clients manage visible gray hair while keeping to their regular color appointments.
