Hot Head™ boosts the effectiveness of any conditioner, mask, or oil by gently opening the hair cuticle, allowing treatments to penetrate deeply rather than stay on the surface. The result is softer, stronger, beautifully nourished hair from the inside out.
Shower caps are essential when using Hot Head! Save yourself a trip to the beauty supply store and add on a 10-pack of disposable shower caps. Or better yet, check out our eco-friendly alternative to traditional plastic shower caps below!

This cap works great and stays warm for several minutes! I did my first masque with it on and my hair had no frizz afterward, which is rare for me.
I went with the XL because I have a lot of hair and I’m glad I did. It’s roomy, but when my hair is clipped up it still fits.
I will say it’s a bit heavier than I anticipated, which could be an issue for some users.
I highly recommend this well made product Chelsea on Sep 14th 2020
I have been “loc’d” for 10 years and I was worried about this cap being able to fit over all of my hair. I’m glad to say it did no problem! Held the heat for a while and my hair is feeling sooooo much better! I’m excited to continue to use this to deepen my moisturizing methods! Thank you!! Loc’d Queen on May 18th 2020
Omg! This changed my hair after 1 use. I have a mix of 4 type hair and my hair loved the hot head thermal cap. My hair has felt great and moisturized all week. Vanessa on May 8th 2020
This is my second Hot Head after buying one for all the women and little girls in my life years ago for Christmas. Of course everyone loved it! I have since out grown my first one. So this time around, I purchased the XL this time. I love the freedom of walking around and doing other things un tethered. As for my hair, this is the healthiest longest my 4c hair has been in my life! Really helped in getting Conditioner to penetrate deeply Into the hair. I gave it 4 stars because you really have to follow the directions exactly. My first hot head was slightly scorch for heating it too long. JW on Apr 20th 2020
When my hair is getting bigger, I’ll let u know but I’m sure it will works wonderfully!! Lol Tiffani on Jan 1st 2020
I purchased this particular hot cap as a gift for my sister, who has longer hair than I do. If the Stellar
XL is anything like the Bloom Hot Head I purchased in September than I know it's wonderful! Absolutely brilliant invention! Melissa on Dec 7th 2019
I had been searching high and low, price wise anyway for a suitable deep conditions cap that was big enough, pretty enough and wireless. After trying other cheaper options this turned out to be amazing. Thank you for making this product Unknown on Sep 23rd 2019
Second purchase. Love how my Locs feel afterwards. Use at least once a month. Tammy on Sep 23rd 2019
I have been natural for over 2 years and let me tell you the struggle is real. Not only being natural but finding products that are made without harsh chemicals as well as the accessories to live a natural curly girl/person life with minimum hassle. I saw a video on YouTube for the ThermalCare Hot Heads cap and could not buy one fast enough. I followed the simple instructions to heat it in the microwave and voíla! The Hot Head went to work and for the first time in years I was free of the cords that tied me to my hair dryer. Free to do other things with my hands and most of all so happy to have found a truly useful accessory to help me manage my hair routine. My only misstep is I purchased an XL when the smaller size would have hugged my head better. No matter this will be with me for life and my hair was deep conditioned, super soft and manageable thanks in part to my Hot Head. Christine on Sep 12th 2019
I have only used the hot head twice since receiving. I am pleased so far with the outcome. It will last about 20-25 minutes before reheating. I'm happy I'm able to do other things without needing to sit under a hooded dryer. This saves me lots of time and decreases the damage most hooded dryers cause. Thanks Hothead! Another staple in my hair care routine!!! Unknown on Aug 18th 2019
