What exactly is a chelating surfactant?

Answer

The simplest way to think of chelating surfactants is as cleaners designed for “hard water.” Hard water can make many types of surfactants inactive or ineffective. A chelating surfactant will work in soft water too, but these special cleaners contain an extra ingredient — one that makes them more effective in hard water. Chelating ingredients are more effective at breaking down “scale” and other types of deposits or films.

Chelating surfactants, when used properly, act like microscopic scrub brushes and remove biofilms from the inside of the tubing. They will also help prevent them from forming in the first place. — Doug Schoon is vice president of science and technology for Creative Nail Design in Vista, Calif.

What’s the cause of the pinkish-red oval area on the pad of my client’s toes?

I have a client who has a recurring problem with her fourth toes during the winter months. Both of her “ring finger” toes develop a pinkish-red oval area on the pad. Then a month later, when I see her again, the skin has become dry and hard like a callus, with the layers of skin peeling away to reveal a deeper, dark epicenter.  It’s extremely painful for her and, needless to say, we do not touch it. But it clears up in the summer when she’s wearing open-toed sandals, so I suspect it has to be due to the boots she wears in the winter. Plus she never puts lotion on her feet or uses a foot file in between visits. What do you think causes this?

What are the big white spots on my natural-nail client’s nails?

I have a client who has been with me for about two years. She used to wear acrylic nails but has been a natural nail client for eight months or so. She has these white spots on her nails — big spots that are dry, but not flaky, right in the middle of the nail. I did try to buff them lightly but they do not come off or grow off. I had a new client come in last week who had the same on her toenails. She said it started after she had a pedicure done at another salon. Can you help?
