🚿 Hair Care & Maintenance:

1. Daily Care Tips:
Comb gently from the ends to the roots using a wide-tooth comb or fingers.
Apply a small amount of leave-in conditioner or argan oil to keep the hair soft and shiny.
Avoid sleeping with wet hair. Braiding your hair before bed will help reduce tangling.
2. How to Wash the Hair:
Fill a basin or sink with lukewarm water.
Add a small amount of sulfate-free shampoo.
Gently dip and lift the hair (do not rub or twist).
Rinse thoroughly with clean water.
Apply a moisturizing conditioner and let it sit for 3-5 minutes.
Rinse well and air-dry the hair on a wig stand for best results.
3. What to Avoid:
Alcohol-based styling products, as they can dry out the hair.
Over-brushing or combing the hair when wet, as it can cause breakage.
High heat (above 180°C / 350°F), as excessive heat can damage the hair fibers.
Extended exposure to chlorine or salt water.
