Hello,Recent works on epiluminescence microscopy has given a good patient compliance in Pseudofolliculitis barbae.This allows proper visualization of the loop of hair and cutting it there.Rest is fine.You are doing what is require to be done but all said and done, the hair sometimes does not follow our rules!
Regarding the good application for Psoriasis lot of external applications are tried and sometimes combinations either of external applications or combined therapy with internal medications.However we are still far away from an ideal treatment for this condition.
External steroids of different potencies,Calcipotriene,Tazoratene,Anthralins,Coal tar,Lactic acid,Salycilic acid,Picrolemus,Tacrolimus,Moisturizers are the applications either alone or in combination.Dry itchy skin responds better to ointment base.
Gels are best for scalp,Axilla and groin respond better to a creme base.Fissures respond best to thick ointments.Occulsion helps in palms,soles and highly thickened skin.Small patches respond well to intralesional steroids.
The drugs are used as combinations,or in rotations,Or sequential therapy starting from high potency with a mild medication for long term.
While I can not recommend you any medications with out examining you hope you will find this useful in learning the different options in external treatment of Psoriasis.
