Abstract: The disclosure herein teaches a method for preserving cosmetics, including hair dye, that are prone to oxidation. The method uses an apparatus for automatically sealing and resealing, so as to prevent oxidation immediately and thereafter the cosmetic products are dispensed, or breached, from their manufacturer packaging. In the proposed apparatus, this is done by producing negative pressure inside a chamber while the cosmetic product is inside an unsealed container within the chamber. The vacuum is produced by a pump connected to an on-off valve, which is directly or indirectly actuated under micro-controlled processes. The one-way flow of air from the chamber to the apparatus' exterior produces negative pressure inside the chamber. Packaging can be sealed by outside influence or sealed by the pressure difference between the outside environment and the inside of the packaging upon the rapid repressurizing of the chamber. These processes prevent oxidation or degradation of the cosmetic product therein.

Abstract: A method of creating color solution, comprises the steps of: receiving color shade solution values corresponding to respective color shade solutions and color shade quantity values corresponding to respective amounts of said respective color shade solutions; mapping each of said received color shade solution values to respective locations where said respective color shade solutions are stored; and releasing into a mixing container said respective color shade solutions in said respective amounts. An apparatus is capable of performing the above steps.
