Why don't hair salons use straight hair combs

The main reason why hair salons do not use straight hair combs is that their effectiveness and durability are not as good as traditional perm methods. ‌‌

Hair salons typically use traditional perming methods such as ion perm or chemical perm, which alter the structure of hair through chemical agents to achieve long-term maintenance of curly or straight hair. In contrast, although a straightening comb can achieve the effect of straightening hair, its effect is not long-lasting and causes significant damage to the hair.
