I've recently tried several pink shampoos to see if they really work for color fading prevention. Honestly, I felt there was quite a difference depending on the product.

Tada's Color Shampoo Pink was surprisingly good. Just leaving it on for about a minute makes the hair that has been bleached a strong pink color. The foam is also fine and dense, which helps prevent uneven coloring, and that’s subtly important. After using it a few times, the red tones become more prominent, so adjusting the frequency based on your preference is a plus. It also seems to contain quite a few repair ingredients, making it gentle on damaged hair.

I also tried Clue's Color Shampoo C.Pink, but this one results in a softer pink tone. It’s aimed at people who want to prevent warm-colored shades from turning yellow. However, the scent is quite strong, and those who don’t like sweet fragrances should be cautious. The rinse feels smooth and not rough, which is pretty good.

MOUTON’s Neo Pink Shampoo is definitely salon-grade, and the color payoff is really good. The color changes significantly after just one wash, making it useful when you want to reset faded bleached hair. It lathers well, and the fruity scent lifts your mood. It also contains plenty of repair ingredients, so you can maintain the color while caring for damage—that’s my recommendation.

Personally, I think the best pink shampoos are those that balance good color payoff with repair ingredients. Some people just want the color, but bleached hair tends to be quite damaged, so products that also care for the hair in the long run are better. If you’re unsure which pink shampoo to choose, it’s worth trying these three first.
