Microwavable Heat Caps for Deep Conditioning
A microwavable heat cap turns deep conditioning into a salon-style treatment at home. Gentle, sustained heat helps open the hair cuticle so conditioners, masks and oils can absorb more effectively – helping leave hair softer, smoother and easier to manage.

Lava Cap Customer Testimonials
This cap has been my favourite step to add into my hair regimen… I feel my products work much better with the added heat

I am obsessed with my new cap! It felt like a true at home spa treatment. Would highly recommend it!!!!

We are in love with our caps - my daughter's hair is thriving!

I love using this cap so much that I've gifted some to a few friends who were delighted, my cousin in particular was thrilled!

Frequently Asked Questions
How long do I microwave Lava Cap?
90 seconds usually, but no more than 2 minutes each time
How long do I wear Lava Cap?
Each Lava Cap treatment lasts 15 minutes.
If you wanted to have a longer treatment then the duration will depend on the hair treatment product you are using. Please be guided by the product usage directions.
Will it work for low-porosity hair?
Yes. Heat caps are a favourite for low porosity hair because gentle, consistent heat helps moisture and conditioning ingredients absorb more effectively. This leaves hair feeling softer, smoother and less dry after wash day.
How often should I deep condition?
A minimum of once every 2 weeks, regardless of hair type
Does it work on all hair types?
Yes - Lava Cap is suitable for use by people with all hair types, curl patterns, and porosities
How long does the heat last?
The warm, gentle heat lasts around 15 minutes.
And if you want a longer treatment after this time then you can either:
- Keep the Lava Cap to enjoy a longer treatment while the Lava Cap traps your body heat to support your hair treatment, or
- Pop it back in the microwave for 60-90 seconds
