"Growing up with straight hair myself, that was all I really knew how to work with," Klum, 38, writes in an essay for the Huffington Post. "It was pretty straightforward: wash, air dry, done."

When Heidi Klum welcomed her first child — daughter Leni, now 7 — the model never thought twice about her little girl’s locks.

“Growing up with straight hair myself, that was all I really knew how to work with,” Klum, 38, writes in an essay for the Huffington Post. “It was pretty straightforward: wash, air dry, done.”

However, shortly after starting a family with husband Seal — the couple are now parents to Henry, 5½, Johan, 4½, and Lou, 22 months — Klum quickly found herself in uncharted waters when it came to her children’s hair care needs.

“Henry, Johan, and Lou — my three youngest — have super beautiful locks,” she raves. “I’ve learned to never brush their curly hair when it’s dry because then it’ll frizz. I use lots of conditioner and detangler … and only go to hairdressers who really know how to cut and style curly hair.”

But despite learning the tips and tricks of dealing with their hair, Klum was thrown a curve ball when her sons suggested a summer shave.

“I’ve let my boys’ hair grow really, really long and just recently they asked me to cut off their beautiful hair!” she says. “I’ve been the one to carefully brush and help them care for it all these years, but I do want them to be who they want to be. I think that’s really important, to allow kids to express themselves — everything from the way they dress to how they want their hair.”

The boys’ request wasn’t just a “simple short,” Klum laughs, leaving her to turn to the experts for the final result.

“They wanted mohawks with special designs to them, so I asked Lamar Odom who did his cool design buzz, and then contacted his stylist,” she reveals. “He gave my kids these buzz cuts with amazing individual designs … great for the summer because they’re cool, in both senses of the word!”
