Top Ten Things We Learned from Chris Rock's Good Hair

10. When referring to black hair, a "perm" is actually a permanent relaxer, not the '80s salon treatment that left you looking like a poodle on Park Avenue.

9. The black hair industry inspires competition of Olympic-sized proportions at the Bronner Brothers International Hair Show in Atlanta, where the winning stylist walks away with $20,000 and a Ford Taurus.

8. You may notice the winner of the Hair Show in the film looks oddly familiar. Stylist Derek J is also the mastermind behind Real Housewives of Atlanta Kim's looming wig line.

7. It is estimated that hair weaves make up 65% of the $9 billion dollar black hair industry, which means A LOT of women, both white and black have them.

6. Most human hair weaves come from India, where hair is worth more than gold and women sacrifice it to their temple. They have no idea who or where their hair is going to, nor do they have any desire to know.

5. Weaves can cost anywhere from $1,000 to $5,000. There are even layaway plans for expensive weaves!

4. The relaxer formula used by African Americans for decades contains the chemical sodium hydroxide, which can erode a soda can in two hours and leave you with serious chemical burns and bald spots.

3. Sodium hydroxide burning is the real reason behind the asymmetrical Salt N' Pepa 'do in their "Push It" video. Not because they were trying to start a new trend.

2. Some women get their daughter's hair relaxed as young as 3 years old in what they call a "kiddie perm." They grow up never knowing anything different.

1. Rock said it best in what will be his future words of wisdom to his daughters when they ask to get a perm, "It doesn't matter what lengths you take to achieve the perfect hairstyle because what's in your head is much more important than what's on your head."
