Helen Hunt is a lovely woman. Her character Jamie on Mad About You sometimes talked about her hair, considering how or whether to let her bangs grow out.

Here with Paul Reiser, Helen is wearing a short, casual tousled hairstyle as the series begins, about chin length, with some bangs.
The color is a fairly bright blonde. She has a very nice upper body I will add:

From Season 1, Helen's hair looks quite lovely in a carefully controlled,
sweeping style with a shock of medium bangs. Still in a short style, the
natural-looking color is beautiful:

Season 2 - Here have a great look at how pretty Helen's face is, just gorgeous. Her hair is swept
up from her forehead and she is wearing attractive small earrings.
This is a darker color than we're used to seeing, it appears almost golden brunette:

Season 4 - Helen's hair is much longer, now in a straight style. Some of
the tresses are tucked behind her ears. Long bangs in her eyes are seen
off to the side. Any curling of the ends is very slight. The sandy color looks nice:

Season 4 finale - Again with the longer length, smooth and bright. Helen's hair is brushed back
on the side below the part, at the right temple. The ends are straight and may have been flat-ironed:

Season 7 - Helen's hair is now quite long -- shiny and beautiful. The color is natural-looking, a nice, slightly darker shade. The ends also look
natural and her hair shows possible evidence of some light layering. But however the look is achieved, the fullness is quite pretty:

of course she had hair help. she didn't do it herself.
