faq

what does it do?

The Hot Booster Cap uses gentle heat to help your favourite hair masks, oils and deep-conditioning treatments absorb more effectively. The warmth also helps create a relaxing treatment experience while supporting blood circulation to the scalp.

how do I use it?

Apply your chosen hair treatment and place the cap over your hair. Select the low or high heat setting and use it for approximately 30 minutes. Always follow the instructions provided with your hair treatment.

which heat setting should I choose?

Choose the setting that feels most comfortable for you. We recommend the high setting for low-porosity hair, as heat can help open the hair cuticle and improve product absorption. Start with the low setting when you are unsure or have a sensitive scalp.

which hair treatments can I use with it?

You can use the Hot Booster Cap with hair masks, deep conditioners and hair oils. Always check the instructions for your chosen product to ensure it is suitable for use with heat.

do I need to wear a shower cap underneath?

No. The Hot Booster Cap has a removable inner lining that protects the inside of the cap, so an additional shower cap is not required.

will it fit my hair?

Yes. The Hot Booster Cap is spacious enough for both short and long hair and is suitable for a wide range of hair types and textures.

what happens if the cap becomes too hot or it turns off?

The cap has an automatic overheating protection function. When activated, you may hear a small click and the cap will automatically switch off. Don't worry, this is just a safety mechanism. It will switch back on when the temperature drops.

In case that doesn't happen, unplug it and allow it to cool completely. Try using it again after a few hours or the following day.

feel free to contact us at info@juvahaircare.com if you need assistance.

how do I clean it?

Remove the inner lining and clean it separately. Make sure it is completely dry before placing it back inside the cap. Do not machine-wash or submerge the electrical part of the cap in water.

why is it not available in my country?

The Hot Booster Cap is designed for countries with a 220–240 V electrical supply and comes with an EU plug. For safety and compatibility reasons, it is not available in countries that primarily use 110–120 V, such as the United States, Mexico and Canada. A 110–120 V version for the US is in development.

Availability is determined by your shipping country at checkout. In supported 220–240 V countries with a different socket type, you may need a suitable plug adapter.

I am amazed

I am amazed. Truly. I keep touching my hair, it's so soft. I have double-processed bleached hair, and live in a dry climate. Most leave in conditioners made my hair sticky; with this, i keep touching my hair because it's so toussle-worthy soft. Seriously, thank you. Your new biggest fan.

Top producten!

Ik volg Niki al voor dat ze haar website lanceerde, haar filmpjes op TikTok & Instagram waren altijd met enorm veel goede info en gewoon ook duidelijk.
Ik heb net zoals haar, zeer poreus, droog haar en door haar olie tesamen met een heatcap, is dit gigantisch verbeterd!
Ik heb onmiddelijk de leave-in besteld omdat ik gewoon geloof in haar producten, ze heeft zoveel kennis en je weet gewoon dat ze deze producten met echte kennis en liefde maakt!
Ik ben fan & zal ook altijd je filmpjes blijven volgen voor de super interessante tips die je geeft!
You go girl ❤️

Forever buying this!

Ik zit al aan mijn 2e flesje. Wat een super fijne, niet overdreven vette olie. Ik merk echt nu al verschil in glans en gevoel in mijn punten. Ik heb fijn dun haar, dus alles wat ik eraan kan doen om lengte te behouden doe ik graag. Ik heb echt super veel aan het haar advies die Niki ook geeft op haar social media. Je merkt echt dat ze dit merk met passie heeft opgebouwd en het is te merken in haar producten! Super benieuwd naar alles wat nog gaat komen!
