Using regular hair products on your blonde highlights can be a bit tricky and depends on the type of blonde highlights you have. Here are some considerations:

1. Synthetic blonde highlights:
   - It's generally not recommended to use regular hair products on synthetic blonde highlights. These products can build up on the synthetic fibers and make them look dull and feel stiff. They can also cause the fibers to become tangled and matte, which is difficult to reverse.
   - Stick to blonde highlights-specific products, which are designed to maintain the texture and appearance of synthetic blonde highlightss without causing damage.

2. Human Hair blonde highlights:
   - Human hair blonde highlights can tolerate regular hair products better than synthetic ones, but it's still important to be cautious. Use a lower quantity of product than you would on your natural hair to avoid weighing down the blonde highlights.
   - Opt for sulfate-free shampoos and conditioners, as sulfates can be harsh on the hair and lead to dryness and tangling.
   - Avoid products with alcohol, as they can be drying and damaging to the hair over time.

3. General Tips:
   - Always perform a patch test on a small, inconspicuous area of the blonde highlights before applying any product all over. This can help you determine if the product will damage or discolor the blonde highlights.
   - Rinse the blonde highlights thoroughly after using any hair product to remove any residue.
   - Regularly condition your blonde highlights to keep the hair soft and manageable. This is especially important for human hair blonde highlightss, which can become dry and tangled over time.

In summary, while human hair blonde highlights can handle a limited range of regular hair products, synthetic blonde highlights should be treated with products specifically formulated for blonde highlightss to maintain their appearance and longevity. Always err on the side of caution and follow the manufacturer's care instructions for your specific blonde highlights.
