    AMERICA'S FIRST ASPHALT PAVEMENT
    July 29, 1870

    Was laid in Newark, N.J. Previously, coal tar was used for many pavements laid in the 1860s. The first recorded asphalt pavement in the U.S. was a sand mix placed in front of the City Hall in Newark, N.J., in 1870. Edmund J. DeSmedt, a Belgian chemist (who became the inspector of asphalt and cements for the District of Columbia) held a U.S. patent for this asphalt paving method, granted on 31 May 1867. In that century most roads, even in cities, were wide dirt pathways, severely affected by weather. Smooth surfaced asphalt roads originally were for the benefit of bicyclists. By 1904, only 141 miles were surfaced, but commonplace by 1916. Natural asphalt deposits were originally used, but almost all of the asphalt used commercially is now made from petroleum.

    THE FIRST IRON LUNG
    July 29, 1927 - United States

    (Electric Respirator) was installed at Bellevue hospital in New York for the post war polio epidemic. The first iron lung was developed at Harvard University by Phillip Drinker and Louis Agassiz Shaw built with two vacuum cleaners. The iron lung is a negative pressure machine which surrounds the patient's body except for the head, and alternates a negative atmospheric pressure with the ambient one, resulting in rhythmic expansion of the chest cage (and thus inhalation) in response to the negative extra thoracic pressure. During periods of ambient extrathoracic pressure, the lungs deflate. This type of machine is rarely used today.

Dark or Natural
Article written June 1, 2010

As summer approaches we hear more requests from our clients that they want to receive the darkest possible sunless tan. Even though it's June, this sends shivers down our spines. As technicians, we want to accommodate our customers but know that darker shades or over spraying your client is not the answer.

The first thing we need to do is to take a deep cleansing breath. Remember the goal of a sunless tan is to look pretty and natural. Advise your clients that a darker level of solution may not look natural on certain skin tones.

Understanding How DHA Works:
The primary ingredient in all sunless solutions is DHA (Dihydroxyacetone). DHA reacts with the amino acids on the epidermis causing a bronzed color to appear. In other words, DHA adheres to the dead skin cells. As the cells begin to shed so does the DHA attached to it.

All sunless solutions contain a certain percentage of DHA. Professional grade solutions can range anywhere from 5% to 12%. A higher percent of DHA will produce a deeper result. Keep in mind the more DHA concentration in the solution the more the color changes from a golden brown to a red brown.

You cannot apply a deeper color by over-spraying your clients. Skin can only absorb a certain amount of solution in a single session. Over-spraying your clients will only waste your solution. In addition, using too high a percent of DHA on lighter skin will produce an unnatural color and have patchy fading.

Many solutions add a temporary bronzer to their solution. DHA take between 4 to 8 hours to fully develop on the skin. Temporary bronzers allow the technician to see where the solution is being applied and gives the client sees immediate color. The bronzer will wash off during the first shower.

Why Are Sol Potion Solutions Unique:
Our solutions were developed to allow the technician to use as is, or blend any combination of the four levels to personalize a shade for your clients. Many of our salons and spas create their own ?beauty bar of shades. By blending your own shades you can make colors that truly match your client's skin tone making it the most natural looking tan for their skin type. These can be premixed and ready for a client session or prepared at the session.

When you have the flexibility of using the proper colors on your clients, they will love the results and keep coming back for more. This will make you stand out over your competition.
