I perfectly understand what you're saying, because that was what happened with my son. He didn't have red hair, but it was kind of reddish (people usually commented), and straight, when baby. Then it became "curly" and blond. My guess is that it'll become wavy and brown in adulthood.
My father and I do have some red in "central beard" only, but I check our SNPs plus my wife's, and we don't have those more important alleles associated to red hair. The reddish in my son must have been associated to additional SNPs.

I get rs1805008 CC, rs885479 GG,
rs2228479 AG, rs1805006 CC, rs1110400 TT and
rs1805005 GT. So only rs2228479 and rs1805005 could explain this little red in beard.
My wife and son get the same: rs1805008 CC, rs885479 GG (inferred for my son), rs2228479 GG, rs1805006 CC, rs1110400 TT and
rs1805005 GT. So only one variant in rs1805005.
Curiously, I didn't have this reddish tone when I was a baby. Theoretically my son's could be related to this "heterogeneity" at rs1805005, however, this result cannot be the whole story, since I get the same result and had different phenotype. My hypothesis is that he also inherited some other allele that caused early high depigmentation that facilitated this little "reddish" shows up. Either way, it was not enough for keeping his hair with that tone.
