To all the ladies in the house

...or at least anyone who knows anything about beauty...

So Shecky's Beauty Week is coming up, and I'm thinking of having my hair professionally colored red. There's only one place offering a discount on coloring, and this is their service rundown:

• Single-Process Coloring Plus Chinois Hair Treatment | SHECKY'S BW PRICE: $50 (usually $135)
• 1/2-Head Highlights Plus Chinois Hair Treatment | SHECKY'S BW PRICE: $75 (usually $175)
• Full-Head Coloring Plus Chinois Hair Treatment | SHECKY'S BW PRICE: $100 (usually $275)

My question is:

WHAT DO THESE MEAN? WHICH ONE DO I WANT? AHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHH!

Thanks.
