10. Scalp Massagers & Hair Growth Devices

At-home scalp massagers, LED combs, and microneedling rollers are gaining traction for their ability to boost circulation and encourage hair growth—benefits typically sought in salon treatments. These tools stimulate the scalp, enhance nutrient delivery, and may help reduce hair shedding. LED devices, in particular, use low-level light therapy to reactivate follicles, with studies showing promising results over time.
