What are the primary methods of hair straightening?

1. Chemical straightening and thermal straightening

2. Twisting and curling

3. Clipping and waving

4. Brushing and drying

The correct answer is: Chemical straightening and thermal straightening

The primary methods of hair straightening involve two main techniques: chemical straightening and thermal straightening. Chemical straightening utilizes specific solutions or relaxers that break down the hair's natural bonds, allowing it to be reshaped into a straighter appearance. This method often provides longer-lasting results, making it ideal for individuals seeking a more permanent solution to frizzy or wavy hair. On the other hand, thermal straightening employs heat, typically through flat irons or blow dryers, to smooth the hair cuticle and create a sleek, straight finish. This method is widely used for its immediate effects and versatility, allowing users the option to temporarily straighten their hair without altering its natural structure permanently. Other methods listed, such as twisting, curling, clipping, waving, brushing, and drying, focus on creating curls, waves, or adding volume to the hair rather than primarily straightening it. Therefore, they do not serve the same purpose as the primary methods of hair straightening which are focused specifically on achieving straight hair through either chemical or heat application.
