Actually, this happened to me. I received unsolicited advice from someone randomly. She did it so smoothly that I didn't realize she had said it all just to help me until like a few days later. (lol)
Conversation:
Me: "Hey girl - man it's hot this summer."
Her: Yeah, you know I've been saying what can I do with this hair (she shakes her newly flat ironed "shiny hair")
Me: Well it looks beautiful!
Her: Well I can only wear it without a bit of oil in it for the first day (she glances at my hair). After that I have to add oil to the ends and it's up in a bun until wash day (she glances at my ends). That's how I keep my length and shine! (she blinks at my hair)
Me: Oh really, wow! I never realized how you protect your hair, that's great.
This was us meeting up for a special event and I had dry looking hair. Yes, it was straight, thick, neatly trimmed and beautiful, but it appeared dry (I had even started a topic about dry hair on LHCF). I already sealed my ends, but her little tidbit informed me that my hair appeared dry to observers as well.
Oh and it was the eye contact she was making with my hair while she was talking that let me know what she meant!
I appreciated the advice and I researched products to use to avoid dry "looking" hair. Now my hair is health AND shiny.
