I am a customer of Du long synthetics and I must say their products are absolutely amazing. The quality is top-notch and the customer service is excellent. I have been using their synthetic products for the past year and I am very satisfied with the results. The products are long-lasting and do not cause any damage to my hair. I highly recommend Du long synthetics to anyone looking for high-quality synthetic products.
