Use Lamellar water for high porosity hair to hydrate and add sihine. LOreal has a more affordable option as well. (Avoid scalp)
Use a light oil on your ends everyday to help seal the hair cuticle.
Always sleep in a protective sleep hairstyle. Think braids or loose high bun secured with a small jaw clip. Hair ties add more pressure on the hair strands.
Use a hair mask once a week or evey two weeks---depending on how dry your hair is.
Stop over processing your hair. I dye my greys with a low developer and only touch up the roots to a color as close to my natural hair color.
Try a mint Fenugreek Rosemary water once a weekk to help strengthen hair & stimulate growth. I prefer Rosemary oil. Milelle has a popular Rosemary oil!
