Systems, devices, and methods for in situ diagnostic assessment and formula dispensing are described. A diagnostic formula applicator can include a fluid dispensing assembly coupled with a comb having a plurality of tines. A tine of the plurality of tines can be configured to dispense a fluid formula to a region of a biological surface via at least one fluid conduit. The diagnostic formula applicator can include hair diagnostic circuitry operably coupled to the fluid dispensing assembly. The diagnostic circuitry can be configured to actuate the fluid dispensing assembly to deliver the fluid formula via the at least one fluid conduit, responsive to determining a user-specific hair cosmetic aspect from hair and scalp sensor information.
