My Buying Guides on Schwarzkopf Professional Color 9-21 Hair Color
When I decided to try Schwarzkopf Professional Color 9-21 Hair Color, I wanted to make sure I understood everything about the product before making my purchase. Here’s my detailed buying guide based on my experience and research, which might help you too.
Understanding the Shade and Color Result
The 9-21 shade is known as a very light ash violet blonde. I was drawn to this because I wanted a cool-toned blonde with a subtle violet hue to neutralize any yellow undertones in my hair. If you’re aiming for a similar result, this shade is perfect for brightening your look while adding a trendy, ashy finish.
Who Is This Hair Color For?
This product works best if you have light blonde to very light blonde hair already or if you’re willing to pre-lighten your hair. I found that trying to use it on dark hair without bleaching didn’t give me the vibrant violet tone I hoped for. It’s ideal for those looking to maintain or enhance their blonde with a professional salon-quality finish.
Why I Chose Schwarzkopf Professional
I trust Schwarzkopf Professional because of its reputation for long-lasting, vibrant colors and quality ingredients that protect hair during the coloring process. The Color 9-21 formula contains care components that helped keep my hair feeling soft rather than dry or damaged.
Application Tips from My Experience
- Always do a patch test 48 hours before applying to check for allergies.
- Follow the instructions carefully: mix the color cream with the recommended developer volume. I used 20 volume developer to achieve the best balance of lift and color deposit.
- Section your hair for even application and process time.
- Keep track of timing—leaving it on too long can alter the shade. For me, 30-35 minutes was ideal.
- Rinse with lukewarm water and use a color-safe shampoo and conditioner afterward to maintain vibrancy.
What I Loved About This Hair Color
- The cool violet undertones really helped neutralize brassiness in my blonde hair.
- It gave a shiny, healthy look without excessive dryness.
- The color lasted well for weeks with minimal fading.
- The professional formula felt salon-grade, making me confident in the results.
Things to Consider Before Buying
- If your hair is dark or previously colored, you might need to lighten it first for the color to show properly.
- The violet tone is subtle but noticeable on lighter hair. If you want a stronger purple, consider mixing with a more intense violet shade.
- It’s a permanent hair color, so be sure you want a long-lasting change.
Where to Buy and Price Considerations
I found this product available at professional beauty supply stores and reputable online retailers. Prices can vary, so I recommend comparing to get the best deal. Remember to also budget for developer and aftercare products if you don’t already have them.
Final Thoughts
Overall, Schwarzkopf Professional Color 9-21 Hair Color gave me the cool, bright blonde with violet hues I wanted, with professional quality and lasting results. If you want to refresh your blonde with an ashy-violet tint and don’t mind a bit of prep work, this shade is definitely worth trying.
I hope my buying guide helps you make an informed choice! If you decide to try it, good luck and enjoy your new hair color!
