A good scalp massager brush can clear product build up that may irritate your skin—and helps rinse away every last trace of shampoo or conditioner. Plus, using one feels great. Here’s what else you need to know about these helpful little tools.

Gentle Bristles

Silicone points are the perfect way to give your head an invigorating rub. They’re not too stiff but not too soft, either. Maxsoft

A scalp massager that’s too rough can scratch the sensitive skin of your scalp, causing pain. But one that’s too soft won’t strip product build-up as effectively. Silicone bristles are the perfect happy medium.

Easy to Use

This product boasts an ergonomic handle for more comfortable use. HEETA

You don’t want a scalp massager that falls or slips all over the place while you’re trying soap up with shampoo, or work a slippery conditioner into your hair. Look for one with an ergonomic handle for the best grip.

Longer Points

This product has extra-long bristles, making it a great option for long, thick, or voluminous locks. Cbiumpro

A scalp massager with short bristles doesn’t stand a chance against thick curls or long hair that gets piled on top of your head as you shampoo. So if you have this type of hair, opt for a scalp massager with longer bristles.
