XL Hot Head™ Microwavable Deep Conditioning Heat Cap
The XL Hot Head™ is our most spacious heat cap — ideal for extra-long or thick hair, locs, braids, or anyone who needs more room for their deep-conditioning ritual.
Circumference: ~21" starting • ~44" fully stretched
It delivers gentle, consistent heat that helps treatments absorb more deeply, leaving hair softer, smoother, and richly hydrated. The XL also doubles as a heat source for setting rollers without damaging tools — simply allow hair to cool fully before removing rollers to lock in curls.
The Stellar XL Hot Head™ pairs a soft purple terry cloth with a vibrant, galaxy-inspired print on the reverse — a celestial touch that brings personality to your self-care ritual.

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!

Great product, works very well. Mel on Mar 16th 2025
I've been using this for a few months now and it's awesome. Keeps the heat well and even if you feel like it's lost the heat before you're ready just throw it back in the microwave again. But I usually get more than 20 mins of strong heat with the way you warm up the cap. And the XL is amazing with my fro. Daniel on Jan 31st 2024
...To my deep conditioning routine. Wonderful idea and beautifully executed cap. Look forward to each time I use it. Unknown on Sep 30th 2023
It's a wonderful conditioning cap. Unknown on Mar 12th 2023
It still works great! It’s so convenient to be able to move about while deep conditioning my hair. I love it. The XL is a good fit for my very long hair. Christine on Nov 21st 2021
This cap is nicely made and convenient to use. It stays warm a long time. I have a 23 inch crown, wavy hair below shoulder length, and ordered an XL. This was the right size for me. I'm happy with it! Unknown on Jul 27th 2021

This heat cap fits me perfectly! I have a lot of hair and this cap is able to cover all of it! The inside of the cap stays warm a lot longer than I thought it would. I highly recommend this heat cap! Unknown on Jan 27th 2021
Most heat caps are too small, but this fit my head perfectly and I have a lot of waist+ length thick hair. I had to heat it up a couple of times to deep condition for an hour. The cap feels like it cools down quick on the outside, but stays warm on the inside. Nichole on Nov 1st 2020
I absolutely love my hot head cap! It made doing protein treatments at home a lot easier. It stays warm for a good while & the lavender spritz was a nice plus. Honestly it was so relaxing I wanted do just take nap with it on lol. Definitely recommend this product! Carrie on Oct 28th 2020
