Many commercial hair oils contain silicones that create artificial shine. While they look good initially, they build up over time and prevent nutrients from reaching hair. This buildup can eventually lead to dullness and breakage.

18. Wheat Germ Oil: The Rancidity Risk

Though nutritious, wheat germ oil goes rancid quickly when exposed to air. Using rancid oil can damage hair and cause scalp irritation rather than helping. Its strong smell can also be off-putting for many users.

19. Excess Essential Oils: The Irritation Cause

Using undiluted essential oils directly on your scalp can cause severe irritation. Even diluted, oils like cinnamon or clove can burn sensitive scalps. These reactions can damage follicles and actually inhibit healthy hair growth.

20. Palm Oil: The Environmentally Problematic Choice

While palm oil contains beneficial fatty acids, its production often involves deforestation. Additionally, it can be too heavy for most hair types, leading to greasy buildup. This buildup can clog follicles and inhibit healthy growth.
