Resistant hair is considered to have what type of porosity?

  1. High

  2. Low

  3. Medium

  4. Variable

The correct answer is: Low

Resistant hair is typically considered to have low porosity. This means that the hair cuticle is tightly packed and does not easily allow moisture or products to penetrate. Options A, C, and D are incorrect because they describe other types of porosity high, medium, and variable, respectively. High porosity hair has a more open cuticle and easily absorbs moisture and products. Medium porosity hair has a slightly open cuticle but still retains some moisture. Variable porosity hair has both high and low porosity areas, making it difficult to predict how products will affect the hair. This is why option B, low porosity, is the best answer for resistant hair.
