The secret ingredient in the small conditioner of the box-dye
What makes hair so soft and silky after dyeing?

May 9th, 2025
If you've ever tried dyeing your hair at home, you probably know that inside the boxes you buy, there's always a small bottle of conditioner that seems like liquid gold for your hair. It seems to contain something that no other conditioner has, making your hair incredibly shiny, silky, and soft, as if it solves every problem. But what makes it so special? And why does it seem like no other conditioner has the same magical effect?
What is the secret ingredient of the box dye conditioners?
Let’s reveal the mystery: the secret ingredient in the conditioners that come with hair dye is amodimethicone. But what exactly is it? It’s a special silicone, a modified version of dimethicone (another type of silicone), which gently bonds to the hair, reducing frizz and leaving it soft like silk. Unlike heavier silicones, amodimethicone attaches only where needed (mainly to the most damaged and worn parts of the hair) creating a protective barrier that locks in moisture and adds shine, offering a targeted and long-lasting treatment. Additionally, compared to other silicones, it doesn’t build up on the hair, preventing it from becoming heavy or greasy over time, making it ideal for every hair type.
All the benefits of amodimethicone
The benefits of amodimethicone are truly numerous! Thanks to its ability to form a protective film, it helps to retain moisture within the hair, reducing dryness and preventing frizz, especially in humid environments or when exposed to external agents. It also protects the hair from the damage caused by thermal tools, such as straighteners and blow dryers, by creating a barrier that minimizes the effects of heat. Amodimethicone detangles the hair, making it easier to comb, reducing knots and tangles, simplifying styling, and preventing hair breakage. Additionally, it helps tame frizz and makes the hair more manageable, giving it a more polished and shiny appearance. A true ally for healthier, protected, and easier-to-manage hair.

Although it might seem like amodimethicone is a rare or hard-to-find ingredient in hair products, in reality, many products contain it, and it's actually quite common. Just check the INCI of the product to find it! You can find it in shampoos, conditioners, masks, and leave-in treatments. Here’s a list of products containing this magical ingredient.
