Which hair type is most susceptible to damage?

Fine hair is most susceptible to damage primarily due to its structure and lower density. Fine hair strands have a smaller diameter, which makes them more fragile and less robust compared to thicker hair types. Because fine hair lacks the same amount of protective layers as coarser or thicker hair, it can easily become damaged from environmental factors such as heat styling, chemical treatments, and even daily wear and tear.

Additionally, fine hair struggles to hold moisture, making it more prone to dryness and breakage. When subjected to stress, such as tugging or pulling during styling, fine hair is more likely to break. Due to these characteristics, individuals with fine hair often need to adopt gentler styling practices and products specifically designed to provide additional strength and protection.
