I agree with everything the ladies have said. I would put just oil in my hair, like almond oil and when it dried it would be dry, greasy and crunchy! I thought oil wasn't working for me. But like the ladies have stated, I too mix my oil with something else. I use an all oil pre-treatment. But after my wash and conditioner, I mix olive oil and castor oil and a little aloe vera and use it as my leave-in. This concoction alone would still leave my hair dry and crunchy. I do use it to treat my hair. But after this, I spray on a concoction of cheap conditioner mixed with Infusium, olive oil, water and activator. I do it daily and my natural hair is not crunchy anymore. Experimenting is important to find what works best for you.
