regrowing hair after chemo
My hair was not coming back after chemo as fast or thick as I’d hoped, so I bought this. I wear it for 30 minutes every other day. I had to ask AI how often and long to wear it, because I couldn’t find that information with the hat papers. It’s so easy to just sit with it on and read a book for 30 minutes. I’ve noticed a measurable difference in the rate my hair is coming in, and it’s less patchy. It’s 100% worth it to me.

Missing parts
Missing main controller so I couldn't even use it - had to return to store for refund. If they have one for replacement and it works OK, I might update this review.

redlight therapy works
It's taking time, but I can see that my hair is starting to grow back in places where I'd lost hope. I've been pretty agreesive with using it every day for 20 minutes, but will be starting an every other day routine to give my scalp a break--slow and steady wins the race. To those out there who are naysayers...it works!

Honestly, packaging was good , built quality is good. Product can be used easily and I wish they add a battery pack to it so we can use it on the go by having a phone app that would control the modes and timer . Now that would be the next level as it could very well be in near future . I would have really appreciated if there is a recommended usage video to go over strict plan of # of days and # of minutes . should we use it 5 days or every other day and how long . This way we know how this product works. No one wants to face challenges with over stimulation with fading results . I look forward sharing results in next 6 months

Works with my Google Charging Block.
Did not work with SLF block that came with hat. I watch videos and then trouble shooted per FAQ. Works with Google Charging Block! I have only used one time. We will see if hairs grow in. I like the built in timer and remote. Of this works, it will be a great value compared to other red light hats.

Purchases as a gift
I purchased this for a gift. I honestly didn't think it would work but it actually does. My dad called me and sent a picture that hes actually getting a couple new hairs that are starting to grow lol He says it comfortable and ge just puts it while hes playing video games.

So easy to use and works
[This review was collected as part of a promotion.] I love that I can put this on and go about my day doing my chores in my home. It is so convenient and I basically forget I even have it on my head. So it is easy to use and I'm already seeing results. I am very impressed and I am definitely going to continue using it.

Helpful device for thinning hair
[This review was collected as part of a promotion.] I ordered this red light therapy cap to help improve my thinning hair. This cap is adjustable and fits my head perfectly. The red light modules are all over the cap so it hits all sides. The multiple settings and timers make this device so easy to use. I just put it on and go about my daily tasks while it works.

I’m happy with this cap
[This review was collected as part of a promotion.] Pretty impressed with this cap so far. It’s easy to use and comfortable to wear, and I like that you can adjust the intensity and timer. Feels like a convenient way to add red light therapy into your routine. Too early to see major results, but overall it seems promising for the price.

Finally results I can see
[This review was collected as part of a promotion.] My hair has been thinning between perimenopause and GLP1 use. Using a combination of topical oils and res light therapy I've seen a significant improvement.

No hassle and an easy swap/addition!
My husband loves how easy and discreet this is to use! He’s been using more often than not and says it’s comfortable which says a lot! He’s already feeling more confident

I am impressed!
[This review was collected as part of a promotion.] I’ve been using this red light therapy hair cap and so far I really like how simple and convenient it is. The inline controller makes it easy to adjust without having to take the cap off, which is a big plus.After using it consistently, I’ve noticed my hair feels a bit stronger and less dull.The cap itself is lightweight and fits well, so I can wear it while relaxing or doing things around the house.

Easy to use
[This review was collected as part of a promotion.] This is easy to use. A hat you can just put on makes it easy, you just put it on, turn it on, choose your desired settings, and you can watch TV or work on your phone, etc. With multiple setting options, you can see what works best for you.

Worth it!
[This review was collected as part of a promotion.] As I get older, my hair doesn’t have the same fullness and “umph” it used to. After doing some research I decided to try this red light cap. I can definitely tell the difference already! The cap is comfy and fits great. I actually like to wear it on my drive to and from work - I just plug it into a usb port in my car. Heal my hair while I drive to work, can’t complain! Lol.

Works great!
[This review was collected as part of a promotion.] I was dealing with post partum hair loss and my hair was juat not looking its best. My neighbor recommended trying red light therapy. I purchased this not really having high hopes but I was quite shocked how well it was working. I noticed less hair coming out when I brushed. My hair was looking nicer and was growing!! This was a great investment in myself and mental health!
