Grow a heads are quirky little heads that grow grass hair when watered! The really neat thing about Grow a Heads is that you can style and personalize them for any occasion.They’re a unique specialty toy that were a big hit at a recent International Toy Fair in New York. I see that they’ve just been added to the AsSeenOnTV site so I thought I’d do a write up and include some consumer comments. I couldn’t help comparing them to Chia Pets. The major difference is that they actually use rye grass for hair which is not as as finicky to grow as the chia sprouts.
