Looking to rescue your locks from the dry wintry weather mix that February can bring? The science of getting healthy-looking moisturized hair is in porosity and humidity, according to Redken’s Understanding Your Hair Porosity guide.
Hair porosity science is your hair’s outer cuticle layer, and it’s like shingles on a roof. Low porosity has tightly closed cuticles that makes it hard to absorb and retain, medium porosity has balanced spacing and absorbs and retains moisture well), and, lastly, high porosity has widely spaced or lifted cuticles which absorbs quickly, but loses moisture fast), often from damage.
Since, hair porosity determines moisture retention you want to aim towards that medium range to keep your hair looking its best.
Evidence-based routines for transitioning from summer to winter hair care, include biotin, keratin, rosemary oil, and nutrients from a balanced diet for stronger hair. The following tried and true rituals also help to protect your hair from breakage caused by extreme weather:
• Using richer conditioners (Shea butter, oils) and deep conditioning weekly
• Reducing the frequency of washes with sulfate-free shampoo
• Applying leave-ins/oils to seal moisture
• Minimizing heat
• Getting regular trims
• Wearing protective styles
• Just leaving your hair alone for the weekend
And remember:
Winter = dry air = breakage
Summer = humidity = frizz
So, be sure to rotate your hair care routine by season.
