Final answer:
There are four SOCOLOR series that are not recommended to be mixed with Extra Blonding Cream. They are SOCOLOR Cult, SOCOLOR Beauty, SOCOLOR Sync, and Ultra Blonde.
Step-by-step explanation:
The four SOCOLOR series that are not recommended to be mixed with Extra Blonding Cream are:
- SOCOLOR Cult - This series is designed specifically for vibrant and bold colors, so mixing it with Extra Blonding Cream may not produce the desired result.
- SOCOLOR Beauty - This series is formulated for complete gray coverage and rich, natural-looking hair color. Mixing it with Extra Blonding Cream may compromise the coverage and color result.
- SOCOLOR Sync - This series is a no-lift, ammonia-free demi-permanent hair color. It is not recommended to mix it with Extra Blonding Cream because it may alter the desired level of lift and tonality.
- Ultra Blonde - This series is designed specifically for achieving ultra-light blonde shades. Mixing it with Extra Blonding Cream may dilute the lifting power and result in a less effective lightening process.
