Is your Sew In hair extension also facing the dilemma of “strong roots, straw-like ends”? This isn’t a quality issue with the product itself, but rather because exposed hair ends experience friction and nutrient loss daily. Daytime damage is unavoidable, but nighttime is the golden time for deep repair. Master these nighttime secrets to let your hair ends rejuvenate while you sleep.
Part 1: Why Are Hair Ends Solely Damaged? Understanding the Root Causes
The hair roots are intact, but the ends are dry, mainly due to two reasons:

Nutritional Deprivation
Hair extensions are detached from the scalp and cannot receive nourishment from the scalp’s natural oils. Every time you wash your hair, nutrients are taken away from the ends, leading to increasing dryness.

Ubiquitous Friction
Friction from clothes, chair backs, and pillows during sleep all fall on the hair ends, causing damage to the cuticles and tangling.
Part Two: Nighttime Repair Combo: A “Deep Spa” During Sleep
Incorporate the following steps into your bedtime routine for amazing results.
Secret #1: The Hair Oil “Sandwich” Sealing Method
This method ensures that nutrients are locked in layer by layer, rather than just sitting on the surface.
On dry or slightly damp hair ends, spray a small amount of water-based moisturizing mist or gently pat on a little leave-in conditioner to provide basic moisture.
Take 2-3 drops of lightweight hair oil (such as argan oil or argan oil), rub it in your palms to warm it, and then evenly apply it to the ends of your hair, avoiding the hairline and roots.
Finally, spray a thin layer of water-based moisturizing mist. This “water-oil-water” step helps the oil emulsify and penetrate better, forming a perfect protective film on the hair surface.
Secret #2: Braid Your Hair to Sleep to Prevent Friction
This is the most crucial step in preventing tangles and friction at night.
Divide your hair into two sections and braid them loosely, letting them hang down in front of your chest. Loose is key; too tight and it will pull on your extensions and your natural hair.
Gather your hair into a loose bun on top of your head and secure it with a coiled hair tie (like a telephone cord hair tie). This minimizes contact with the pillow.
Secret #3: Upgrade your last line of defense – silk pillowcases
Why it works: Compared to cotton pillowcases, silk has extremely low friction, which greatly reduces moisture loss and tangling of hair during sleep.

Saving dry, brittle hair ends is a battle of consistent, nighttime repair. Remember: all moisturizing products should be strictly avoided at the roots and seams, focusing only on the ends starting below the ears. Usually, just 3-5 nights are all it takes to feel that lost smoothness again.
