Why my wounds regenerate slowly? i eat proteins and live a healthy life style, and still my wounds don't heal fast?

Nutrient deficiency: This may be partially genetic but even so optimal nutrition should help. Make sure you are taking a well-absorbed zinc supplement such as zinc picolinate 30 mg/day as well as other trace minerals. Take Vitamin C (1000 mg 2x/day) and eat colorful fruits for flavonoids. Horsetail root for silica may help. You might also be hypothyroid so see a nutrition-oriented doc to evaluate for that.

Try Vit C and Zinc.: Assuming you don't have any specific medical condition that makes healing more difficult, you can assist your healing by supplementing vitamin C and zinc.
