    Help-customer nail complaint

    I agree with Selina’s very good advice and would add there is no way that I can conceive of that wearing any type of nail coating can cause a loss of the nail plate when properly applied, maintained and removed. If that were the case, it would happen all the time and not just in isolated cases...

    UV Product Summary

    Also, as my most recent Education Update explains (see below), it is VERY important to replace the original bulbs with the SAME bulbs that came with the UV nail lamp that was designed to cure the UV gel of your choice. This is VERY important, so please share this information widely...

    UV Product Summary

    Hi Melissa, LEDs are a type of UV nail lamp, in fact LED create more UV than fluorescent-style bulbs. No UV curing nail product works with any type of UV lamp. You must use the lamp that the manufacturer has tested and shown to properly cure the product of your choice. I have written many...

    OMG-one hand is darker than the other!

    I suspect both companies would tell you that you should not do this. If you like a product well enough to purchase it, you should follow the manufacturer's instructions and not make up your own directions.

    OMG-one hand is darker than the other!

    That's an excellent question. Thanks for asking. If a company can't tell you how to properly cure the product, they must not care if their products are properly cured or are unaware of the potential issues related to improper cure of nail enhancements. Either way, I would not use the product...

    OMG-one hand is darker than the other!

    I know that many nail professionals try this, but if you think about it, how can you proper evaluate a UV gel if you use the incorrect nail lamp? I don’t think you can. Here is a link to an Education Update that I wrote about this subject. My advice is, if you can’t afford or don’t want to...

    OMG-one hand is darker than the other!

    I disagree with you claims. The output of these nails lamps is too far low to cause the tanning you described, nor would you “instantly notice” that your skin was darker. That’s not how the skin tanning process works. Tanning would not occur instantly under any circumstance, nor are these nail...

    Artichokes and Shellac?

    Admittedly, I’ve not tested this claim, but I find it to be pretty unlikely and have seen no evidence to suggest otherwise. Just because something seems to be true, doesn’t make it so. I wouldn’t accept a claim based on two occurrences, esp. when the claim is pretty unlikely. As Carl Sagan was...

    UV Product Summary

    JTB, Your method for determining cure is flawed and will produce incorrect results. Heat spikes are not just proportional to the amount of photo initiators, nor do heat spikes give any indication of how the product is curing, other than “too fast”. This is but one component that must be...

    Help with client starting chemo, please

    Hi Anf, Chemotherapy can affect the way that hair and nails grow, but changes in the nail matrix are the reasons for changes in nail's growth pattern. The color or types nail coatings on the nail plate are unlikely to any effect on the nail plate when it comes to chemotherapy. The reason the...

    Shellac: Why isn't it a gel polish?

    Hi All, I wanted to provide a little information on this subject. Of course, I can't tell you too many secrets, because you know what I'd have to do... LOL. Shellac is indeed a unique product, unlike anything out there and different in many ways. It was developed over a five year period, so...

    Catalysts and Initiators

    To clarify, catalysts speed up or slow down chemical reactions. They DO NOT initiate them. For instance, benzoyl peroxide is the initiator in liquid and powder systems, while DNPH is a typical catalyst that speeds up these reactions and makes the initiator work more quickly. There are dozens of...

    About UV and UV LED's and the differences scientifically.

    Hi, The information presented on the Pure Spa blog cited above is incorrect and appears to be intentionally misleading. In my opinion, that site should not be considered a credible source of information and should be avoided. Months ago I posted a reply on the Pure Spa blog to correct this...

    Some people just CAN'T wear nails...?

    Hi Victoria, I don't think that's convincing. Given how many people are on some type of anti-depressants these days and the fact that most people can wear artificial nails, I'd think it is more reasonable conclude the exact opposite. It appears to be highly unlikely that anti-depressants cause...

    Some people just CAN'T wear nails...?

    It is unlikely that the nail will suddenly change in composition. If it did, it would take months before the new composition dominated the nail plate, since the nail's composition is mostly determined in the matrix. My guess is that except for long term health problems, e.g. heart surgery or...

    Some people just CAN'T wear nails...?

    Hi, Not everyone is a good candidate for wearing artificial nails. This can happen for a wide range of reasons. They may be secret pickers and their problems are self-inflicted or they may have their hands in cleaning solutions or in water too much or they may possess overly thinned/damaged...

    Fresh Monomer Every Time?

    The problem with these pumps is that monomer liquid becomes contaminated with Benzoyl Peroxide (the curing agent) from the powder and is then allowed to mix with fresh monomer... which is not right. In a dampen dish, that is ok since the product is discarded. With these pumps, the contaminated...

    How to work with really oily nails?

    Of course sebaceous glands produce lots of oil, but oil can migrate from many places and the body can produce small amounts without these glands. I would tend to agree that much of it is probably transfered to the nail plate from areas.

    How to work with really oily nails?

    Hi Envy, Good advice and info. As you point out, there is some oil in the nails and it has a similar composition to skin oil, but of course the hair has much more for the reasons Victoria described. Even so, the so-called "oily nail" issue is over exaggerated and often used as an excuse for...
