- Q
I have two questions. 1) Does this have a heat protectant in it? 2) I shower and wash my hair in the morning, can this product be used as my leave in after my MORNING wash or is there a specific reason i must use at night? My hair needs exactly what this product offers, just not at nightime. Thanks!
- Asked by D
- Official Answer By Joico - Brand EngageHi D! Thank you for your questions. The Defy Damage Sleepover Overnight Nourishing Treatment does not contain a heat protectant. We would recommend the Defy Damage Protective Shield or the Dream Blowout Thermal Protection Créme for heat protection. You can use the Treatment in the morning. The normal recommendation is just a few pumps before bed-no need to rinse-just wake up and glow. It’s that easy! We would recommend to apply evenly to clean dry or towel-dried hair at bedtime. Avoiding root area. Leave in overnight-no rinsing necessary. It can be used 2-3x a week or as needed. Hope that helps clarify! ✨💕Was this answer helpful to you

Can hot tools be used after applying
- Asked by Roxx
- Official Answer By Joico - Brand EngageHi Roxx! Thank you for your question. The Defy Damage Sleepover Overnight Nourishing Treatment does not have thermal protection. For thermal protection from tools, we would recommend the Heat Hero Glossing Thermal Protector or the Defy Damage Invincible Frizz-Fighting Bond Protector which both offer thermal protection up to 450°.

This one is a keeper!
I really like this product! I use it in the evening after washing and conditioning my hair and let it air dry in. I feel like it gives it nourishment through the night and when I wake up, I feel good about it having a layer of protection during the day. Despite it is directed for use as an overni...

Itchy scalp
I started using this product every night recently and my scalp was itching nonstop like CRAZY, it felt like sharp itchy pains on my head all of the time. I had also started using new shampoo and conditioner so I thought maybe it was that, but once I excluded this from my everyday it went away. It co...

Doesn't Do Anything
This product did not soften my hair as promised, and it really didn't do anything at all. And the scent is a sickeningly strong, plastic-cheap-perfume smell that I also find repulsive. I have pretty damaged, dry, straight, thick, heavy long hair due to root touch-ups. It responds well to Olaplex treatments in salon, as well as home maintenance products from Olaplex. I really enjoy Joico's Defy Damage line of shampoos, masks, and other leave-in treatments, but this Overnight Treatment did nothing for my hair. I used it both sparingly AND completely drenched my hair in it, and the next morning, my hair was still dry, rough and damaged- feeling and damaged-looking. Completely pointless, it was a terrible waste of money
My hair must have
Hair Type Straight Hair
My hair grows very fast and is naturally oily so I wash it daily. I use this for the ends of my hair. I never have split ends and my hair is shiny and soft. I love all of the joico products.
Great overnight hair treatment
Hair Type Straight Hair
I have thick medium length hair. This hair treatment is so easy to apply. I applied 3 pumps of treatment on the bottom half of my hair and put on silk cap to protect the hair overnight. In the morning, my hair feels smooth and shiny after styling. Highly recommended.
loving this!
I'm loving this! I have curly / wavy hair and this smells great and leaves my hair so soft after years of bleaching for vibrant color. All without weighing it down or leaving it greasy. My new GOAT leave in conditioner.
Loving it!
Hair Type Wavy Hair
Loving this! I have bleached hair for vibrant color and needed deep conditioning. A little goes a long way and i noticed a huge change with one application. I like leave in conditioners better. Smells great too. I will definitely keep this one!
