Yes, hair that has broken off will eventually grow back from the follicle, but the broken portion itself will not reattach or repair.
Here's a more detailed explanation:
-
Hair Growth Cycle: Hair grows in cycles. Each hair follicle goes through phases of growth (anagen), transition (catagen), and rest (telogen), before eventually shedding and starting the cycle again.
-
Breakage vs. Root Issues: The key distinction is whether the hair is breaking off along the shaft due to damage or whether the follicle itself is no longer producing hair. Breakage is damage to existing hair, while problems at the root prevent new hair from growing.
-
Causes of Hair Breakage: Many factors can cause hair to break, including:
- Heat styling (e.g., using flat irons, curling irons, and blow dryers).
- Chemical treatments (e.g., perms, relaxers, coloring, and bleaching).
- Over-brushing, especially when wet.
- Tight hairstyles (e.g., braids, ponytails, and buns).
- Environmental factors (e.g., sun exposure, dry air, and wind).
- Nutritional deficiencies.
- Friction (e.g., from clothing or sleeping on a rough pillowcase).
-
Addressing Breakage: To minimize breakage and promote healthy growth:
- Use heat protectant sprays before styling with heat.
- Limit chemical treatments.
- Be gentle when brushing your hair, and use a wide-tooth comb on wet hair.
- Choose loose hairstyles over tight ones.
- Eat a balanced diet rich in vitamins and minerals.
- Consider using silk or satin pillowcases to reduce friction.
- Use deep conditioning treatments or hair masks regularly.
- Trim damaged ends regularly to prevent further breakage.
-
New Growth: While you can't "fix" broken hair, new, healthy hair will continue to grow from the follicles. Focusing on hair health can minimize future breakage as the new hair emerges. The reference states: "In most cases, hair replenishes itself by growing back to maintain a full head." This refers to the follicles continuing to produce new hair growth, replacing the strands that have broken off.
In summary, broken hair won't magically repair itself. However, the follicle beneath the scalp remains capable of producing new hair. By addressing the causes of breakage and adopting healthy hair care practices, you can minimize future damage and encourage strong, healthy growth.
