- Detangle Gently: Before washing, use a wide-tooth comb to gently detangle your hair, starting from the ends and working upwards.
- Condition Properly: Apply conditioner only from the mid-lengths to the ends of your extensions to avoid weighing them down.
- Dry Carefully: Avoid towel-drying, which can cause frizz. Instead, gently squeeze out excess water and let your extensions air-dry.
- Sleep Smart: Tie your hair in a loose braid or ponytail before bed to prevent tangling. Consider using a silk pillowcase to reduce friction.
- Don’t Sleep with Wet Extensions: Avoid going to bed when your hair extensions are still wet. This helps stop tangles and keeps them smooth.
- Store Clip-Ins Properly: When not using clip-in extensions, keep them in a dry, flat place. This keeps them neat and ready to wear.
- Deep Condition Often: If the extensions are made from real hair, use a deep conditioner regularly to keep them soft and healthy.
- Limit Heat Styling: Try not to use heat tools too much. Less heat means your extensions will stay in good condition longer.
Styling Tips
- Blend with Natural Hair: Curl or straighten your natural hair and extensions together to make them look natural.
- Use Heat Protectant: Before styling with heat tools, always apply a heat protectant spray to prevent damage.
- Try Different Styles: Braids, ponytails, or loose waves show off the length nicely.
- Be Gentle: Avoid pulling or tugging hard while styling to protect your hair and extensions.
- Match Color and Texture: Choose extensions that match your hair color and texture for a natural look.
