In Case You Missed It...

Lindsay Lohan's had a very busy day! And it looks like all the drama is pushing her over the edge...

Early on Wednesday, she got her stringy hair all soft and fluffy again at the Byron & Tracey salon. LiLo, back to red = Hottness!

But dinner at Nobu with her mom and sis didn't go so well - the 22-year-old "looked horrible," "didn't want to talk to anyone" and only "drank water the whole time."

The final straw came late at night, when our photogs heard a shouting match between Linds and Dina, prompting the troubled starlet to storm out of the house, hop in her BFF Patrick's car and speed away.

Break-ups, not eating and non-stop fighting? Lindsay is on a downward spiral and needs some serious help. But is rehab really the answer?

She's already done that three times!
