As a blonde I know all too well what chlorine does to hair.  I swear I spent most of my life before 18 with "snot green" hair.  Back then we had no idea what the pool chemicals were doing to our hair.

Being in the pool alot, you need to make sure the chemicals are being removed from you hair or they will dry it out.  There are shampoos out there specifically for swimmers, Ultra Swim is one my son and I both have tried.  It worked OK, not fantastic, but OK.  What we both found worked best was Aussie Mega shampoo and Aussie 3 Minute Miracle conditioner.

If I know I am going swimming now, I will put conditioner or jojoba oil in my hair before swimming (jojoba for lakes, conditioner for pools).  Then rinse with clean, fresh water when you get out.

What are your events?  I used to compete when I was a kid - distances were my specialties - 500m, 800m and the mile.

What's your current best time and the school record for the 50 free?

That's a pretty decent time - congrats!  If you work hard you should be able make your goal!  Hang in there and swim hard!
