Choose oil by purpose and instructions
Scalp oil, a pre-wash treatment and an oil or serum for the lengths can have different instructions. Do not automatically use them in the same way. Choose a product for the area you want to care for and follow its amount, processing time and rinsing directions. Scalp oiling is not necessary for everyone.

How much hair oil should you use?
Start with a small amount spread between your hands. Work through lengths and ends if the product is intended for them, adding only a little at a time. A fixed number of drops does not suit every bottle and formula. Aim for an appropriate finish, not visibly oily hair.
Fine or short hair often needs less than long, coarse or dry lengths. Avoid overloading roots if hair flattens easily. Curly hair does not automatically need more oil; assess whether curls feel softer and more manageable or simply heavy.
Before washing, on damp hair or on dry hair
Before washing: use oil only as recommended. Apply to the stated areas and follow its processing time rather than a fixed rule of several hours or overnight. Wash out as directed and condition according to the lengths' needs. Heating it in a water bath is not necessary.
After washing: a leave-in formula can be applied to damp, towel-dried lengths. Squeeze out water without rubbing and use a small amount. Oil does not replace conditioner or leave-in, and ordinary hair oil is not automatically heat protection.
On dry hair: apply a little suitable oil or serum for finish and shine, especially to ends. Avoid new layers all over if only a few areas need attention. This is styling and conditioning; it does not permanently repair split ends.
A simple application routine
Gently loosen knots from the ends in small sections with a suitable tool. Spread the product between your palms and smooth or scrunch it in according to hair type. You do not need to brush through dry curls to distribute oil. Stop when the finish suits you and wash your hands afterwards.

How often should you use hair oil?
No weekly frequency suits everyone. Adapt to the directions, scalp needs, washing and how quickly lengths become coated. A pre-wash treatment and a little finishing oil on ends are different uses. Daily use is not necessarily better, and you do not need more on days when hair already feels appropriately conditioned.
If you have used too much oil
Stop adding more. A small excess on the ends may be gently blotted with a clean towel. If hair feels noticeably greasy or coated, wash with your usual shampoo and rinse thoroughly. Avoid vigorous rubbing, harsh cleaning agents or very hot water to remove oil.
Frequently asked questions
Can all oils be used on the scalp or overnight?
Only if the product is designed for it and its instructions allow it. An oil for lengths should not automatically be applied to the scalp, and a pre-wash treatment should not automatically be left overnight.
Is hair oil heat protection?
Not necessarily. Use a product designed for heat protection as directed. The name hair oil does not itself indicate protection from a dryer or straighteners.
Can I use both leave-in and oil?
Yes, if they suit your routine. Leave-in and oil have different functions; start with small amounts and follow the recommended order. If hair becomes heavy, reduce amounts or product numbers rather than adding another layer.
