After unwrapping her hair, she was thrilled to find it had returned to its original blonde colour, showing no signs of the earlier green tinge.

Once her hair was almost completely dry, it looked as if it had never been green at all.

While some commenters recommended purple shampoo, one person clarified: "Purple shampoo doesn't take out green, it tones yellow."

They elaborated: "It worked for my hair. Her kind of blond hair would turn green because of chlorine traces in the water. It happened to me every hair wash when I had it."

Another suggested using a "heavily pigmented purple shampoo" could be beneficial.

How does ketchup turn green hair blonde again?

Ketchup can rectify pool-green blonde hair due to the colour theory and the chemistry involved.

When blonde hair adopts a greenish tint, it's typically because of exposure to chlorine and oxidised metals, like copper, in swimming pool water.

These elements attach to the hair strands and give them a green hue.

Ketchup, which is red thanks to the tomatoes, acts as a neutraliser because red is opposite to green on the colour wheel.

When applied, the red pigment in the ketchup counteracts and nullifies the green tint, aiding in restoring a more natural hair colour.

Ketchup is also acidic from the vinegar and tomatoes, which may help in breaking down the chemical build-up from the pool, allowing the greenish discolouration to fade further.
