I use Amla as a treatment (I couldn't leave it in, the smell is too bad) and I use Vatika oil as my everyday oil.
I leave the amla oil in for a few hours and if I'm too tired to wash it out I wrap my hair in a bag and go to sleep. I may add some conditioner depending on my mood. I've been transitioning for a year and this oil lets the comb just glide through my hair.
I use vatika oil on a daily basis when I want a little extra softness and shine.
These oils are really good for detangling, shine/sheen, and bringing out soft waves in my hair. I've been wearing my hair in a boring bun for a good while now and people comment on how pretty my hair is all the time, so I love recommending these oils to anyone who will listen, lol.
The vatika oil is $2.99 and the big bottle of Amla oil is $3.99 - so even if they don't rock your world, you won't feel too bad about the prices.
