To seal your ends properly you must saturate your ends with water. Placing moisture onto your ends can only be done by water and water alone. Water can penetrate the hair shaft and reach the cortex layer of the hair. Depending on the porosity level of your hair some naturals, may need a thick butter or oil to maintain a long lasting seal.
I find Sweet Georgia Peach Hair Butter or 24k High Shine Pomade by Terra Veda Organix works perfectly for maintaining the moisture on my ends till my next seal treatment. Remember the oil/butter's job is to protect the moisture (water) that was just absorbed by your cortex. More protection equals longer lasting moisturized ends. www.terravedaorganix.com
