When applying HD lace glue for a short curly wig, it is crucial to allow the glue to dry until it becomes tacky before putting on the short curly wig. This typically takes about 10 to 15 minutes. Here are some key points to ensure proper application:

1. Apply a Thin Layer: Start by applying a thin layer of glue along the hairline. Avoid applying too much glue, as this can lead to a messy hairline and potential lifting.
2. Wait for Tackiness: Allow the glue to dry until it becomes tacky but not fully dry. This usually takes around 10 to 15 minutes. The tackiness helps create a strong bond between the lace and your skin.
3. Apply Multiple Layers if Needed: For a more secure fit, especially if you are highly active or in humid conditions, apply a second or even third layer of glue. Each layer should be allowed to dry until tacky before applying the next.
4. Press the short curly wig into Place: Once the glue is tacky, carefully place the short curly wig onto your head and press the lace into the glue. Use a comb or your fingers to ensure the lace adheres well to the glue.

Additional Tips:
- Clean Your Skin: Make sure your forehead is clean and free of oils or moisturizers before applying the glue.
- Avoid Overlapping: Do not apply glue directly on the edges of the lace to prevent damage to the lace.
- Test the Glue: Always perform a patch test on a small area of your skin to check for any allergic reactions.

By following these steps and allowing the glue to dry properly, you can achieve a secure and natural-looking fit for your HD lace short curly wig.
