From candy-colored lavender, turquoise, and rainbow manes to the subtler allure of natural colors, hair treatments give us any look we want — but only at the risk of fragile, stiff, breakage-prone strands. That’s why all Plex products strengthen treated hair by rebuilding each individual hair strand’s protein bonds.
pH Plex’s active ingredient, Malic Acid, is small enough to penetrate the hair very effectively. It is also able to react with all amino acids that make up the hair proteins. This makes pH Plex best suited to protect from and repair all damage created during color and bleach treatments.
At the same time, pH Plex’s worldwide patented formula matches the pH value of hair color and bleach. It neither shifts your color nor requires prolonged development times of your bleach or a higher developer concentration. Also, pH Plex is proven to NOT react with hair color or bleach. Therefore, it does not create any concerning reaction or degradation of products during those treatments.
Yes, this is a bold statement. So we’re going to back it up by diving into the science of “why”.
Why Hair Treatment Damages Hair
To understand how pH Plex protects against hair damage, let’s first review how that damage is caused.
Permanent and semi-permanent hair colors, and bleach products, contain hydrogen peroxide. This is essential to create the hair color you desire or to break down the melanin — hair’s natural color pigment. Bleach is even more aggressive to your hair compared to hair color, due to the bleach powder involved.
However, peroxide not only creates your color bonds or breaks down the melanin, but it also breaks your hair’s essential protein bonds (also called ‘peptide’ bonds). Since most of your hair is made out of protein (amino acid chains), breaking those bonds essentially breaks your hair.
Without a protein bond-rebuilding product like pH Plex, you’ll be left with a lovely color but a less lovely case of damaged, limp, partially dissolved hair.
How Malic Acid Products Protect and Rebuild Your Hair
Since hair damage is caused by (1) breaking the Peptide bonds of hair proteins and (2) the bonds in-between protein chains, professional Plex products use active ingredients to penetrate into the hair and to rebuild those bonds. Different from conditioners that work on the outside of the hair, the hair surface, Plex products work inside the hair.
How effective Plex products are is defined by:
- How much active ingredient is in the formulation to start with
- How effective the active penetrates into the hair
- What’s the chemical nature of the active ingredient – meaning with how many of the at least 14 different amino acids of the hair proteins can it react with
- Does the active ingredient react with color or bleach, not only because this can create a potentially concerning reaction, but it also takes away the active ingredient and reduces its availability to do the job of protect and repair
Since all Plex products contain different active ingredients, in different concentrations, it is not surprising that the effectiveness by which they strengthen hair varies.
Malic Acid is the Superstar of Hair & Skin
pH Plex’s active ingredient ‘Malic Acid’ is a compound naturally created by the human body. It is formulated in a super high concentration for maximum effectiveness. Malic Acid is also a really small molecule that penetrates the hair very effectively. It can also react with ALL amino acids of the hair proteins. All of them! And lastly, it is proven to not react with hair color or bleach.
It can’t get any better than this and the reviews don’t lie! Many of our users have shown dramatic improvement in their hair after just one treatment with pH Plex.
An amazing benefit of pH Plex is that it is designed for use at home or in the salon. It doesn’t shift your hair color or prolong the development time of your bleach. It also doesn’t require a higher developer concentration, so it is easy to apply!
Better Hair days with pH Plex
pH Plex’s active ingredient, malic acid, belongs to the chemical class of alpha-hydroxy-acids (AHA’s). This is a main ingredient in many skin care products. While developing pH Plex, malic acid was shown to reduce itching and burning sensations during color or bleach treatment. This was even true for customers with very, very sensitive skin (like neurodermatitis).
pH Plex products protect and repair your hair from the inside out — not just bits and pieces of it.
