For the scalp, e.g. if your scalp is dry
You need something that is light, so it doesn't clog up the pores and very rich in Vitamin E to nourish the scalp :
- Lightest oils: jojoba, coconut oil and argan oil. Jojoba has the added advantage of having a similar structure to sebum - the oil that the scalp naturally produces for itself;
- Most nutrient-rich oils: avocado and argan oil are very rich in vitamin E (they both have more vitamin E than olive oil.)
You need an oil whose fatty acids can penetrate the hair fibre. Why?
According to the Science of Black Hair, hair swells when it is wet and shrinks when it is dry. This constant swelling and shrinking is called hygral fatigue; overtime it weakens the hair fibre thereby making it more vulnerable to breakage. You can avoid hygral fatigue by applying an oil that is high in saturated fatty acids and/or monounsaturated fatty acids before the shampoo. These types of fatty acids can penetrate the hair shaft so that when you wash the hair, the hair fibre doesn't swell as much and is therefore less prone to weakening from hygral fatigue.
The best oils (from the one with the highest content of saturated fats and/or monounsaturates):
- Jojoba oil (100%: 98% monounsaturates, 2% saturated)
- Coconut oil (97%: 6% monounsaturates, 91% saturated)
- Avocado oil (88%)
- Olive oil (86%)
- Sweet almond oil (71%)
Sealing in moisture
The best oils (from the one with the highest content of polyunsaturated fatty acids are):
Castor oil (89%)
Flaxseed oil (73%)
Grapeseed oil (70%)
Note that most oils should keep well for a year plus except flaxseed oil whose shelf life is only 6 months! You can prolong the life of flaxseed oil by keeping it in the fridge. Some oils have an almost indefinite shelf life, e.g. castor oil and jojoba.
How about this whole acid/alkaline thing?
For the most part, oils are weakly acidic. However, even if the oil is weakly alkaline it doesn't mean it will cause you any harm. Try it and decide whether or not your hair agrees with it.
But ... oils make my hair dry!
If you think an oil is drying your hair out it could mean you're using it wrongly. Remember oils are NOT moisturisers. Oil and water repel each other so to get the benefit of an oil use a proper moisturiser first, e.g. leave-in conditioner and oil should follow after that.
