How should chemical hair straighteners be applied?

1. Evenly throughout the hair while avoiding the scalp

2. Only on the scalp area

3. In small sections with excessive product

4. Only at the tips of the hair

The correct answer is: Evenly throughout the hair while avoiding the scalp

Chemical hair straighteners should be applied evenly throughout the hair while avoiding the scalp to ensure uniform results. This technique allows the product to adequately straighten the hair without causing damage or irritation to the scalp. Applying the straightener evenly helps to achieve a consistent texture and appearance, as some areas might react differently if the product is applied unevenly. In contrast, concentrating the application only on the scalp area can lead to over-processing in that region, resulting in damage and an uneven straightening effect. Applying the product in small sections with excessive product may lead to buildup on some strands, which can cause damage or unnatural results, and applying it only at the tips neglects the roots and mid-lengths, leading to inconsistent straightening. Thus, the correct method emphasizes the importance of even distribution while being cautious around sensitive areas like the scalp.
