To appreciate how it works you must have a basic understanding of the proteins that hair needs, so here is a crash course:
Keratin is the main protein in hair and it is a water-soluble protein which is extremely strong. (Horns of animals are formed from this stuff, that’s how tough keratin can be). The Keratin has some chains of amino acids which include cysteine which is what makes keratin so tough.
If your hair needs a revival you will need these proteins:
- Hydrolyzed proteins in rinse-off products (ding ding; that’s one for the DRC-28)
- Collagen for elasticity
- Keratin for strength and to improve the feel
- Wheat protein also for strength
- Soy protein to enhance moisture or bolster normal porosity
- Silk protein to soften your strands
The DRC-28(affiliate link) is deep penetrating, which allows it to build the hair from within by fortifying weak areas. So rather than simply sitting on the hair it can actually get inside the cortex and work its magic. It is said that hair is made up of 22 proteins and amino acids, but the composition of the DRC-28 includes up to 28. This may be part of the reason that this product is making waves. Further investigation of the composition of the DRC-28(affiliate link) revealed that it has hydrolyzed proteins. Part of the packaging content from a bottle reads:
Dudley’s DRC 28(affiliate link) is a deep-penetrating advanced hair treatment and fortifier that is concentrated with most of the hair’s own natural protein and amino acids. This rich formula works from the inside out – nourishing, restoring and repairing severely damaged or weakened hair to a stronger, healthier state.”
Notable ingredients include: Hydrolized Animal Protein, Hydrolized Keratin Protein, Biotin(affiliate link), Panthenol (Vitamin B5), and Hydrolized Glycosanminoglycans (shown to promote hair growth in in clinical tests)
Deionized Water, Hydrolyzed Animal Protein Propylene Glycol, Polyquaternium-11, Glycerin, Polysorbate-20, Panthenol, Acetamide MEA, Hydrolyzed Keratin Protein, Sodium PCA, Methylparaben, Hydrolyzed Glycosaminoglycans, Fragrance, Biotin(affiliate link)
Well, now the picture is a little clearer because even though protein is great for hair and absolutely vital to its existence, not all proteins are created equal. In case you are a little lost, basically, in order for protein to be most effective, the molecules have to be at the right size to be able to penetrate the hair, but not all of them can do that. For instance, when we break an egg and slap it on our heads, this does well to condition the cuticle layer but it doesn’t necessarily get inside the cortex so issues within the strand don’t get addressed. Proteins with the word ‘hydrolyzed’ before them means they went through a process that allows them to be small enough to penetrate the hair or to be absorbed.
Have you noticed how many times hydrolyzed appears in the ingredients list for DRC-28? That may offer some insights into why the reviews are so great. In addition, that Glycosanminoglycans has the cysteine in there and did you notice biotin a Panthenol?
