Redken Extreme Length Collection Now In Stores!

I spotted a new Redken line over the weekend at Ulta called Extreme Length.  It claims to help your hair to grow up to 6" in a year (vs. the average 3").  I'm all for my hair growing twice as fast! Wonder if it really works?
There are two products available so far:

Extreme Length Sealer ($24)- Redken Extreme Length Sealer for all types of distressed hair.
Benefits:

• Formulated with biotin
• Extreme Length system of Shampoo, Primer and Sealer helps achieve your maximum length -up to 6" in a year
• Leave-in treatment helps prevent damage and breakage
• Helps reduce the appearance of split ends

Extreme Length Primer ($22)- Redken Extreme Length Primer for all types of distressed hair.
Benefits:

• Formulated with biotin
• Extreme Length system of Shampoo, Primer and Sealer helps achieve your maximum length -up to 6" in a year
• Provides weightless conditioning
• Builds strength from root to tip

I'm trying to grow my hair out again, so I really want to try these! I've had really good results with most Redken products I've tried, so I'm hopeful for these.  What do you think? Are you interested in trying these?
