Cleveland Clinic

Explanation
No. Hair oils can temporarily improve the appearance of split ends, but they do not permanently repair the existing split. A smoother-looking strand is not evidence that the damage has healed.
Cleveland Clinic describes oils as a temporary way to conceal split ends. Its separate explanation of olive oil explicitly distinguishes reducing additional breakage from repairing existing damage. The American Academy of Dermatology explains that the exposed hair shaft is nonliving and cannot heal itself.
Cosmetic improvement and protection from further damage are different outcomes from permanent repair. An oil may help hair look or feel smoother without reversing an existing split, and results vary with hair type and the oil used.
Key takeaway
Less visible damage is not the same as permanent repair. Hair oils can improve appearance without healing split ends.

Does brushing your hair 100 times a day make it healthier?

Does a 'hypoallergenic' cosmetic label in the US guarantee no allergic reactions?
No. 'Hypoallergenic' does not mean allergy-proof. The FDA has no federal definition for the term, and products carrying it can still cause allergic reactions.

Does shaving make facial or body hair grow back thicker?
No. Shaving cuts the hair shaft without making it grow thicker. Short regrowth can feel coarse and look more noticeable because of its cut ends.
