Save $500 on a red light helmet that regrows hair for Prime Day

You might feel like you’ve tried everything to save your thinning hair or stop the never-ending shedding, but have you tried a red light therapy helmet?

It might sound a little unusual to strap a device to your scalp, but according to users, the iRestore Hair Growth System is seriously effective for hair regrowth. This FDA-cleared helmet features 82 medical-grade lasers and LEDs designed to target your hairline, sides, and crown in every session. And now, for a limited time only, the device is 38% off for Prime Big Deal Days.

Several clinical studies have shown that red light therapy supports hair regrowth by stimulating cellular energy in hair follicles. Some research even suggests it can be effective in treating conditions like androgenetic alopecia, a hereditary condition also known as male-pattern baldness.

iRestore customers have reported seeing results in as little as the first month. One 42-year-old reviewer shared that after trying countless hair loss treatments with little success, the iRestore system finally delivered enough that even others began to take notice.

“Within the first month, I definitely noticed that I was not shedding or losing nearly as much hair as I used to…” he explained. “Hell, after the second month I noticed newer, smaller hairs growing, and after a few haircuts that my existing hair was healthier and thicker. The lady who cuts my hair asked me what I’ve been doing differently.”

If you’re ready to take hair regrowth seriously, this Prime Day deal might be the perfect purchase. Besides, a $500 discount doesn’t come around often, and neither does a second chance at your hairline.

Meet the iRestore Professional, a clinically studied red light therapy solution designed to combat hair thinning and stimulate regrowth. It uses 282 medical-grade lasers and LEDs to deliver low-level light therapy (LLLT) directly to the scalp. No meds, no messy serums. Backed by FDA clearance and real user results, it’s built for both men and women experiencing genetic hair loss. Just 25 minutes a session, hands-free, with an ergonomic design that fits comfortably into your routine. Oh, and it’s $500 off for Prime Day.

Your Prime Big Deal Days FAQs, answered

What is Prime Big Deal Days?

This annual Amazon sale — which we like to call October Prime Day — is similar to the well-known July event: it’s a two-day blow out shopping event with deep discounts on bestsellers and everyday essentials. But the timing of this sale makes all the difference; shoppers can also score pre-Black Friday deals on top-rated toys and sell-out-risk gifts before the holiday rush.

How long does Prime Big Deal Days last?

Amazon’s fall Prime Day event only lasts two days. This sale starts on Tuesday October 7 at 12:01 a.m. PT and runs through Wednesday October 8 at 11:59 p.m. PT.

When does Prime Big Deal Days end?

Prime Big Deal Days 2025 ends on Wednesday October 8 at 11:59 p.m. PT, so east-coasters have until about 3 a.m. on October 9 their time to shop the deals.

When is the next Prime Day?

Already wondering when Amazon’s next Prime Day is? Prime Day takes place in July each year, so it’s safe to assume it will take place in mid-July 2026 — similar to previous years.
