Pilar cysts, also known as trichilemmal cysts, are benign, keratin-filled cysts that commonly appear on the scalp. While they're generally harmless, their appearance can be bothersome, leading many to seek removal. A common question following removal is: will the hair grow back? The answer isn't a simple yes or no, and depends on several factors.
What Happens During Pilar Cyst Removal?
The procedure for removing a pilar cyst varies depending on its size, location, and the dermatologist's preference. Small cysts might be removed through a simple incision and drainage, while larger ones may require surgical excision, where the entire cyst is removed. The surgical method is more likely to result in a noticeable alteration to the surrounding tissue.
Will Hair Grow Back After a Simple Incision and Drainage?
If the cyst was removed via incision and drainage, there's a higher chance of hair regrowth in the affected area. This is because the procedure primarily focuses on removing the cyst's contents and not the surrounding hair follicle itself. However, some minor scarring might occur. The hair that does grow back might be slightly different in texture or density, depending on the extent of damage to the follicle during the procedure.
Will Hair Grow Back After Surgical Excision?
Surgical excision, which involves removing the entire cyst and some surrounding tissue, has a lower likelihood of hair regrowth. This is because the hair follicle is removed along with the cyst. While some minor hair growth may eventually return due to the body's natural hair regeneration, full regrowth to the previous density is not guaranteed. The area might be left with a noticeable scar, depending on the size and location of the cyst and the skill of the surgeon.
What Factors Influence Hair Regrowth After Pilar Cyst Removal?
Several factors influence whether hair will grow back after pilar cyst removal:
- The Method of Removal: As discussed above, incision and drainage offers a better chance of regrowth compared to surgical excision.
- The Depth of the Cyst: Deeper cysts often necessitate more extensive removal, potentially impacting hair follicle integrity.
- Individual Hair Growth Cycle: Individual variations in hair growth cycles play a role. Some individuals have inherently faster hair regrowth than others.
- The Skill of the Surgeon/Dermatologist: A skilled surgeon will strive to minimize damage to the surrounding hair follicles during the removal process, improving the chances of hair regrowth.
- Post-Operative Care: Following the post-operative care instructions meticulously will help minimize scarring and inflammation, both potentially affecting hair growth.
How Long Does It Take for Hair to Grow Back?
Hair growth is a gradual process. If hair regrowth occurs, it might take several weeks or even months to become noticeable. The rate of regrowth varies between individuals.
What if Hair Doesn't Grow Back?
If hair doesn't grow back after pilar cyst removal, it's usually due to the removal of the hair follicle itself during the surgical procedure. In these cases, the resulting scar might be noticeable. The possibility of hair transplantation might be discussed with a dermatologist or cosmetic surgeon.
Can I Prevent Pilar Cysts From Recurring?
Unfortunately, there's no guaranteed way to prevent pilar cysts from recurring. Maintaining good scalp hygiene and keeping the scalp moisturized can help reduce their formation, but recurring cysts are a possibility.
