The main points are as follows: 1. Is it a wig made of rayon or real hair? 2. Is it a hand-crocheted wig or a mechanism wig? 3. Is it a professional wig replacement agency? Is it a personalized wig made by a real person or a wig bought directly in the market? 4. Is the wig net cover made of DLMF ultra-thin silk bionic scalp breathable bottom or ordinary net material? 5. Whether it is tailor-made by professional hair weaving and replacement technicians according to your hair thickness, head shape, face shape and hair loss area, or after being introduced by a shopping guide, 6. Whether the wig is trimmed according to your head shape and face shape and your original hair before wearing it, etc. It affects whether your wig looks fake as a whole, not just your forehead. Generally speaking, as long as you have genuine and fake hair customized by professional hair weaving and replacement institutions, or high-end wigs purchased by professional brand companies, the effect is already very good. For example, Doremi uses seamless and invisible technology to customize the replacement method, which is hand-crocheted with real hair. The replacement technician will carefully design it according to your head shape, face shape, skin color and hair thickness, so that the realistic effect of the braided wig can reach the level of authenticity, so that you don't tell others, so the replacement is like filling teeth and changing clothes. For example, a person who fills a tooth has a porcelain tooth, and you can't see that he fills a tooth, and the same is true for changing a tooth. Real hair, reissued braided hair and good technology can make a real wig, just like your own, without worrying about others seeing it. If others can see it and you are not satisfied, you can also pay the replacement agency without paying. Therefore, many replacement agencies have put forward the slogan "Pay only when you are satisfied". I hope this answer can help you.
