However, here's some information that might help:
* 5N (Goldwell) is a light brown with golden undertones.
* 5A (Goldwell) is a light brown with ashy undertones.
Generally, to achieve a darker shade:
* Use a darker level: A 4N or 4A would likely be darker than a 5N or 5A.
* Use a developer with a higher volume: This will provide more lift and create a darker result.
Here's a possible scenario:
If your current hair is a light brown with some warmth, 5N might be too light, and you might want to try 4N. Alternatively, if your current hair has some ashiness, 5A could be too light, and you could use 4A.
Remember:
* Consult a professional hairstylist: The best way to ensure you achieve the desired hair color is to consult with a professional hairstylist. They can assess your hair condition and suggest the right products and techniques for you.
* Patch test: Before applying any hair color product to your entire head, always do a patch test on a small area of your skin to check for any allergic reactions.
Overall, the best way to achieve a darker shade is to use a darker level of hair color and a higher volume developer. However, it is crucial to consider your current hair color and the desired shade before choosing the right products.
