From understanding the unique properties of gray hair to learning how to protect it from environmental damage, we'll cover everything you need to know to make your silver strands shine. Let's dive into the world of gray hair care and discover how to make the most of this natural and stunning hair transformation.
The Science of Gray Hair: Understanding Its Unique Properties
Gray hair is typically rougher and drier than pigmented hair. With age, hair loses density, shine, and pigment, and the oil glands in the scalp produce less sebum. Compared to straight gray hair, curly gray hair can be even more dry and wiry than pigmented gray hair.
It is also important to remember that contrary to popular belief, gray hair is not white but transparent like glass. It generally has higher dye uptake (semi-permanent or permanent) during hair coloring treatments. This is potentially due to the higher level of porosity and surface roughness, which facilitates the penetration of chemicals. In general, all gray hair types can strongly uptake chemicals agents, conditioners, and oils.
Gray hair is transparent because it has lost its melanin. Melanin has a protective effect against ultraviolet radiation (UVR). Gray hair lacks this natural protective mechanism making it more sensitive to the sun’s rays, which results in the oxidation of hair proteins. That is why white and gray hair is more likely to oxidize, looking yellow and tarnished.
How does caring for gray hair differ from non-gray hair?
Gray hair needs more moisture than non-gray hair. It is important to do a weekly deep conditioning (home) treatment and using a moisturizing leave-in and/or cream. It is also better to use gentle cleansing products to prevent drying and frizz. Especially, sulfated shampoos have this effect on gray hair and can cause frizz, dryness, and yellowing.
Because gray hair is susceptible to yellowing, one should cover gray hair if in bright sunlight for an extended period of time.
How to strengthen gray hair, and protect it from damage
Gray hair is not necessarily weak (this is an incorrect assumption) so it may not need to be strengthened. In fact, non-gray hair can be weaker than gray hair if the hair is not healthy. It depends on the individual.
Other ways to keep gray hair healthy is primarily by addressing any nutritional deficits. Vitamin and mineral deficiencies may cause hair loss and thinning, as well as dryness; especially deficiencies in vitamins D, C, and B12, or if iron levels are too low.
Good nutrition is key to keeping hair healthy and if needed, consult a doctor about taking other nutritional supplements, such as collagen.
The following also play a role in keeping gray hair healthy:
High heat from blow dryers, sulfated shampoos, prolonged exposure to sunlight, hard water, pollution, and product build up, to name a few, decrease shine and make gray hair dull. So, to keep gray hair soft and shiny, we must do the exact opposite.
Some medications can also make gray hair dull and bland and need to be discussed with a medical professional.
Other ways to keep gray hair healthy include weekly deep conditioning treatments and using a (silicone-free) hair serum to seal the outer cuticle layer of the hair to keep moisture in. Sealed cuticles make it easier for light to reflect off gray hair to give the appearance of health and shine.
To keep gray hair healthy, only use gentle clarifying shampoos and avoid sulfates which are especially drying for gray and curly hair. Using a charcoal, ACV or other detox type product weekly or biweekly, also keeps silvers as white as possible. And keeps the scalp healthy.
Seal in the moisture with a cream followed by a film forming humectant gel to coat the hair strands. Sealing in moisture and smoothing the cuticle layers keeps curly gray hair shiny and white.
Tips for embracing gray hair
When you grow out the gray, one tip is to reevaluate your entire look. The colors you used to wear may need to be updated. Your grays may benefit from a more flattering hairstyle. A change in your haircut, glasses (shape and color), lipstick shades, and clothes can significantly enhance your complexion and keep the motivation going.
Using “clean” products and practicing healthy habits will make your hair and scalp healthier as well. Depending on how long your hair is, the process of growing out your silver can take 6 to 36 months. And remember, you can always change your mind and use semi-permanent dye or temporary colors, if you do not like how the grays make you look or feel.
