When caring for human hair wigs, it's important to avoid common mistakes that can damage the wig or reduce its lifespan. Here are some key pitfalls to avoid, based on the latest expert advice:

1. Over-Washing
- Mistake: Washing the wig too frequently can strip natural oils and lead to dryness or frizz.
- Solution: Wash your human hair wigs every 7-10 wears, or when it starts to feel heavy. Use sulfate-free shampoos and conditioners designed for wigs.

2. Incorrect Washing Techniques
- Mistake: Scrubbing the wig harshly during washing can cause tangles and weaken the hair.
- Solution: Gently lather the shampoo and rinse thoroughly without excessive rubbing. Focus on the mid-lengths and ends.

3. Improper Drying Methods
- Mistake: Rubbing the wig with a towel or using high heat for drying can cause tangles and damage.
- Solution: Gently pat the wig with a towel and let it air dry on a wig stand. If using a hair dryer, opt for a cool setting.

4. Excessive Heat Styling
- Mistake: Using high-heat styling tools frequently can dry out and damage the hair.
- Solution: Limit the use of heat styling tools and always apply a heat protectant spray before styling.

5. Rough Handling
- Mistake: Brushing the wig too aggressively or using the wrong tools can cause breakage and frizz.
- Solution: Use a wide-tooth comb or a detangling brush and start detangling from the ends, working your way up to the roots.

6. Neglecting Regular Maintenance
- Mistake: Skipping regular brushing, washing, and conditioning can lead to buildup and tangles.
- Solution: Establish a routine for wig care, including gentle brushing and timely washing with suitable products.

7. Improper Storage
- Mistake: Storing the wig in a cramped space or not on a proper stand can lead to tangling and loss of shape.
- Solution: Use a wig stand or mannequin head for short-term storage and a silk or satin-lined box for long-term storage.

8. Using Harsh Products
- Mistake: Using regular hair products instead of wig-specific ones can damage the fibers.
- Solution: Use specially formulated wig care products such as mild shampoos, conditioners, and leave-in treatments.

9. Sleeping in the Wig
- Mistake: Sleeping in the wig can lead to tangles and damage.
- Solution: Remove the wig before sleeping and store it on a wig stand.

10. Over-Dyeing or Chemical Treatments
- Mistake: Frequent dyeing or chemical treatments can weaken the hair fibers.
- Solution: Seek professional help for any significant color changes or treatments.

By avoiding these common mistakes and following proper care guidelines, you can maintain the beauty and longevity of your human hair wigs.
