1. Scalp Health:
Keep your scalp clean for healthier braids. Wash your scalp every 1-2 weeks with a sulfate-free shampoo. This helps maintain your braids while keeping your scalp fresh.
2. Drying:
After washing, gently pat your braids with a towel to remove excess moisture. Avoid rubbing hard to prevent frizz and looseness. Allow your braids to air dry completely. If in a hurry, use a blow dryer's low heat setting and keep a safe distance.

3. Moisturizing:
Nourish your scalp regularly to prevent dryness and maintain the look of your braids. Use a water-based moisturizer or natural oils like coconut oil, jojoba oil, or shea butter. Apply carefully to keep your braids neat and tidy.
4. Bedtime Care:
Protect your braids while you sleep. Use a satin or silk scarf or pillowcase to reduce friction and prevent frizz. This helps your braids look great in the morning.

5. Maintenance Routine:
Your Bohemian Square Braids can last 6-8 weeks with regular touch-ups depending on care and hair growth rate. Schedule touch-up sessions to manage frizz, unraveling, and new scalp growth. Avoid going longer than 8 weeks to prevent tangles in your natural hair.
6. Caring for Human Hair Curls:
Gently finger comb your human hair curls daily to keep them tangle-free.
1-2 times a week, refresh your curls with a leave-in conditioner, hair tonic, or a mixture of your favorite hair oil and water. Be generous when applying.
Gently comb wet hair to maintain its shape.

By following these steps, you will help your Bohemian Square Braids and human hair curls stay beautiful and vibrant. If you have any questions, feel free to contact us at business@cvohair.com.
If you're going for a protective style that gives your scalp breathing room, installing crochet braids directly onto your natural hair is the way to go. Here's a quick breakdown:
1. Grab Your Crochet Hook
Make sure your hook's latch is open before you start. You don't want it snagging your hair or the crochet strands.
2. Insert the Hook Under the Braid
Slide the crochet hook under your braid hair, starting at the back or sides. This gives you better control and ensures the loops are neat and even.
3. Loop the Hair Through
- Place the crochet hair on the hook.
- Close the latch.
- Pull the hair through, creating a small loop.
4. Secure the Hair
- Take the ends of the crochet hair and pull them through the loop.
- Tighten the loop gently to secure the hair in place.
- For extra hold, repeat this step and create a double knot-especially if the hair is silky or slippery.
5. Work Row by Row
- Continue looping and securing the hair row by row.
- Space the hair closer together for fuller styles and further apart if you're going for a more natural look.
6. Fill in the Front and Edges Last
Save the front and edges for last so you can control the placement. This gives you a more seamless, natural hairline.
