I have purchased this product 3 times. I love it. It arrived on time, the pricecwas perfect, and it did its job. I have some grey hair that I wanted colored. The coloring last 6 months for me. So I color my hair every 6 months. The last time I used this dye was in August 2025 and I just ordered the dye on February 5, 2026. I love this dye. At the 6 month mark I start to notice the grey reappearance. I have no complaints about this product. The 1st an 2nd pictures are from August, 2 weeks after I dyed my hair and the 3rd picture is 3 months after I dyed my haircelestine
