I'm Egyptian and I've recently tried this remedy which a family member from an older generation told me about and it's, by far, the best I've ever tried. I used to have dry frizzy hair till I used this remedy which really softens and adds shine to your hair, straightens it and makes it slightly less frizzy.
Ofc feel free to double or triple what's written below according to your hair length and thickness.
Get a bowl, add a small cup of olive oil, a small cup of liquid bone marrow (no, not bone marrow extract oil, buy actual bone marrow from the butcher and heat it till it turns to a liquid) and an egg yolk and mix them together.
I got grossed out too at first but trust me, it doesn't smell as bad as it sounds and it doesn't feel gross when you touch it.
Apply a generous amount to your hair thoroughly, don't forget your roots and leave it on your hair from 3 to 4 hours and wear a bath cap. Rinse well and shampoo about 2 times to get rid of it all and not to have any remains. I would suggest not to condition so you can see what this remedy solely does to your hair and not mix its results with what your conditioner normally does to your hair but feel free to do so.
You will notice the difference even after trying it only one time. Soft, not to mention SO SHINY hair!
Use this remedy twice a week for 3 weeks to get the maximum results.
Hope this helps and tell me what you think!
