I am truly impressed with the results of Olaplex No.4 Although the initial cost is higher than other brands, the durability of the product is amazing because a tiny amount goes a long way. The high quality ingredients have noticeably strengthened my hair, and I love the subtle, clean scent it leaves behind. It has become a staple in my routine, and I find that using it with a regular frequency keeps my hair looking healthy and shiny. It is definitely worth the investment for professional level hair care.

Great Shine and softness , my hair looks smoother and healthier. The consistency is perfect , packaging is practical. Rinsing is easy and it doesn't weigh my hair down

This really worked for me to help nourish and prevent damaged hair. I dye my hair often so the upkeep is important to prevent long term damage. Olaplex is one of few brands that has made the best impact.
