Final answer:
Winding hair on rods with too much tension can lead to hair breakage, hair loss, and scalp damage, making 'All of the above' the correct answer.
Step-by-step explanation:
When hair is wound on the rods with too much tension during styling treatments such as perms or curling, several problems can occur. The excessive tension has the potential to cause hair breakage, hair loss, and scalp damage. These issues arise because the hair shaft can be weakened due to overstretching, and the scalp can become stressed from the excessive pulling forces applied. This results in the correct answer being 4) All of the above.
