ACV may also help manage frizz and improve overall hair texture. When the cuticle lies flatter, the strands can feel smoother and become easier to style. This may reduce the appearance of frizz while helping the hair maintain moisture and softness.

Some people consider leaving diluted ACV on their hair overnight, believing that longer contact provides greater benefits. However, overnight use is generally unnecessary and may increase the risk of irritation, particularly for people with sensitive scalps.

Using ACV safely is important. It should always be diluted with water rather than applied directly to the scalp or hair. If burning, redness, itching, or other irritation occurs, the treatment should be rinsed out immediately and discontinued.

Overall, ACV can be a simple addition to a regular hair-care routine. It may support shine, smoother texture, reduced buildup, and a cleaner-feeling scalp. However, its effects are usually gradual, so it is best considered an occasional treatment rather than a miracle solution.
