The life-giving, warm, and powerful Sun (the only star in earth's solar system) rules the external ego of all with this natal ascendant. You tend to radiate, to generate, and give "light" to others and the environment. You are perhaps more effective and much happier if you create and cause things to happen rather than merely imitate or reflect that which is all about.
Ego is accented, especially since the Sun (ruler of the inner self) is also ruler of the outer self. This causes you to be much the same person within and without. The traditional fifth-house characteristics of youthfulness, pleasantness, and good humor are frequently brought to the obvious and conscious levels of your everyday life.
While most individuals with Leo ascending tend to be from average to slghtly above average in height, the body is strong, with a full trunk; limbs are usually proportionate. With many, the head is rather large and roundish. The hair is fine and may be light in color; it may grow rather low on the neck.
The eyebrows may be thick and well-formed. The skin texture usually is very good and should appear quite healthy. The teeth may be unusually white, well-formed, somewhat large, and evenly spaced. The voice is full-toned; the speech pattern may be rather decisive and often commanding. Others tend to listen and obey -- especially when you "roar" like a lion.
The "showy" nature of Leo causes you to love colorful clothes and all other kinds of adornments. There may be a "natural" taste for the "loud," and it's entirely likely that at times you may slightly overdo good taste in your dress. Regardless, everything you wear must (or should) be of the best quality you can afford.
