Henna‘s pigment, lawsone, gradually migrates into the hair shaft while setting and will naturally & gently bind to the keratin(protein) in your hair. It will actually maintain your current natural highlights and undertones.
You asked, how does henna bind to hair? When the henna leaves paste is applied to the hair, its active dye molecule, Lawsone, gradually migrates into the outer layer of the hair binding to hair protein creating a fast stain. The Lawsone essentially sticks to the hair without having to open the cuticle and washes off after a few washings.
Correspondingly, how does henna bind to keratin? When you pulverize the leaves and mix them with a slightly acidic liquid such as lemon juice, the dye molecule becomes available as the cell walls’ cellulose dissolves. The dye molecule can then migrate out of the paste, breach cuticle cell walls in the hair shaft, and bind with the keratin.
Likewise, does henna penetrate hair shaft? Henna hair dyes coat the cuticle, or outer part of the hair shaft, and do not penetrate the cortex of the hair, where the hair’s proteins and moisture are housed. This means that henna provides shine and conditioning to the hair, and the cocoa butter is deeply hydrating.
Additionally, how do you activate henna? There are a lot of different techniques that people use when mixing their henna to improve its staining ability, including mixing with lemon juice, apple cider vinegar, strong tea, etc. Once the henna is mixed with the liquid, it needs to sit for 12-24 hours to become fully “activated”.Henna is not a protein treatment. However, it works to strengthen the hair like protein. It contains tannin molecules that bind to the keratin fibers in the hair and winds around them, making the strands physically stronger. Thus, the hair feels similar to a protein treatment.
