Holographic powder isn't exactly new. Spectacular? Yes. New? Not really. SpectraFlair has been a popular polish additive for years. the difference now is how its used. The holo of old was added to existing polish to give it a holo sheen but balancing the ratio could be difficult. Too little and you see no effect. Too much and you end up with grey sludge. The new powders in holo, chrome, and multi chrome that have recently exploded into popularity are buffed into the nail after it is polished. The coverage is surprisingly complete and I believe it uses significantly less of the precious powders.
One of the first pigments available in brick and mortar stores. I got this at Sally's Beauty Supply a few years ago. (yeah this review has been sitting in my queue for years.) SuperNail came out with Chrome, Rose Gold and Holographic. Of course I had to go with Holo. It was also a great time to use my Seche Vite UV lamp I got on clearance years before but never had polish to go with it. Pigment powders work best with a UV/LED No Wipe Top Coat.
Its really very easy to use. Just paint with the top coat, cure it under a light, use the eyeshadow applicator to pick up just the tiniest bit of powder, and buff it into your cured polish. That's it. All there is to it.
Literally this is all the powder you need for one nail.
This is Layla holo nail polish (with a little stamping for flair). I've yet to find a regular top coat that doesn't "eat" the holo effect so this is not top coated and wears away at the tip.
More Layla polish with no topcoat. Ring was with Black Holo, others with regular Holo.
Holo powder buffed into the nail with another coat of No Wipe on top of it so that it shines too! Index and ring have a coat of black under the top coat, the others are naked. I'm in love with powders and now have a large collection of tiny pots of powder.
