A lot of her DIY's sounds really simple so I decided to try one out for myself, the Leave-in conditioner spray, it's incredibly simple and I'm so happy with this!
I used an old Lee Stafford heat protection spray bottle that I never really liked because of it's incredibly strong and chemical smell. Plus I never straighten my hair because mine is like 99% straight naturally anyways.
For my conditioner I used my detangling conditioner for kids by Rainbow Research (yes, I'm that sensitive, and my hair gets tangled really easy and it hurts so much to brush it out :( ) and for my oils I used up the rest of an Moroccan Argan Oil sample and a little bit of olive oil. So where I live the tap water is totally fine to drink and doesn't contain any bad things at all so I just filled it up with tap water and shook like hell!!!
It makes my hair feel super soft and smells nice. I might just have to label it though so it doesn't get mixed up with the heat protection though!
