Hair care for long hair: the routine that preserves your lengths and prevents split ends
Hair care for long hair is about protecting the lengths from dryness and mechanical damage. Use conditioner every time you wash, a hair mask every other week, and always rinse with cool water to preserve the cuticle and prevent split ends.
Long hair is old. The ends of long hair can be several years old and have been exposed to years of washing, heat, and friction. This means the lengths need more active care than the roots to maintain their strength and shine.
Cleansing: gentle is key
Shampoo only your scalp, using light, circular motions. Let the lather rinse through the lengths as you rinse it out, without rubbing. Rubbing creates friction that opens the cuticle and speeds up split ends. A sulfate-free shampoo bar is especially good for long hair because it cleanses gently without drying out the lengths.
Conditioner: essential every time you wash
Long hair needs conditioner every time you wash it, without exception. Apply from the ears down, focusing on the ends. Glycerin binds moisture in the strands and keeps the lengths hydrated between washes. Rinse with cool water to close the cuticle and add extra shine.
Hair mask: every other week for long hair
Long hair benefits from a deep-conditioning hair mask every other week. Apply to the lengths and ends, leave it on for 10-15 minutes under a shower cap, and rinse thoroughly. This restores moisture and nourishment to the oldest parts of the hair and extends the life of the lengths.
Split ends: prevent them instead of repairing them
Split ends can't be repaired, only cut off. That's why preventative care is essential for long hair. Avoid heat without heat protection, sleep on a silk pillowcase, and never use elastic bands directly on your hair. Learn more about how to prevent split ends and what causes them.
The Editor's Note: Trim your hair regularly, every 10-12 weeks, even while growing it out. It sounds counterintuitive, but small trims remove split ends before they travel up the strands and cause more damage.
