Meaning of "the lock of someone's personality" [closed]

I'm reading The Sellout by Paul Beatty. It says:

There weren’t many memories left. Most, like the suit of armor from which Spanky recited Mark Antony’s soliloquy in “Shivering Shakespeare” under a barrage of peashooters, the lock of Alfalfa’s personality, the top hat and tails Buckwheat wore when he conducted the Club Spanky Big Band and made “hundreds and thousands of dollars” in the “Our Gang Follies of 1938, ...”

What does "the lock of Alfalfa’s personality" mean here?

Solution 1:

All the references go to the "Little Rascals" and "Our Gang" shorts which ran from 1922 until 1944.

Spanky, Alfalfa, and Buckwheat were all recognizable characters based on certain physical attributes.

Alfalfa's trademark was his freckles and an untameable "cowlick"; hence the 'lock' reference, as in a lock of hair.

He was quite a presumptuous little fellow, with an over-blown opinion of his own appeal to the opposite sex...
