Table 3.

The mean number of hair follicles in control and treated groups examined under high power field per 10 mm after 21 days of treatment with KCZ solution 2%, Minoxidil solution 5%, and Minoxidil solution 5% with Tretinoin solution 0.1%. This table shows that hair follicle number increased insignificantly (P value > 0.05) in all treatment groups.

Groups	Mean number of hair follicles/10 mm	P value
Control	5.200 ± 1.92
KCZ	9.600 ± 3.20	N.S.
Minoxidil	13.600 ± 2.50	N.S.
Minoxidil and Tretinoin	8.200 ± 2.58	N.S.
