To the original poster I quesion what type of "Sikh" refers to the 10th maharaj without including SINGH in his title???

Having read your post and seen that you have considered the God argument and that everyone else has already guided you towards Gurbani and relevant scholarly resources on the subject, I won't hit you with any further religious dogma.

Let me share with the non-dogmatic reasons of keeping my hair (I didn't always do so):
1. Hair is natural. Living in a natural state means living in a simple state.. This has significance when you're attempting manage your vices (e.g. ego) and promote your virtues (contentment). With cutting your hair you would have to keep getting it cut, worry about your appearance (ego). It means you are not content with your natural state (doing nothing your hair will grow). If you are male and have a beard, shaving becomes a daily ritual. Shaving can cut and wound and cause skin burn. You constantly worry about your personal physical appearance. I want others to see beyond what I look like and for them to see my inner personality. Not worrying about cutting or styling my hair or the perfect length of stubble etc also has an impact on helping to manage lust. Why is a bald woman considered unattractive? Because hair has sexual mate-attracting functions. Cutting and styling it means you are (perhaps inadverdently) trying to vye for sexual attention. If you claim no worries, I'm keeping it covered- then might as well stop cutting it. Indeed hair-cutting was a phenomenon brought about by Alexander the Greek Invader (who was also bisexual and very much liked short hair on men). Until recently many cultures even in Europe have maintained long hair and beards. In the 80's, long hair and a beard was all the rage in the West due to popular culture, now the popular culture is short hair and a stylish goatee. Who will you follow, ever changing popular culture or do you want to be timeless?
2. Hair, being natural, has a scientific purpose. We have evolved to the point where there are very few redundant body parts and organs. The Appendix no longer processes grass etc but it does still serve a purpose. Compared to cows, it is very small. There are remnants of a tail bone where, if you accept the theory of evolution, there would have once been a tail. Hair however is still as long and wonderful as it was hundreds and thousands of years ago as it is now. Evolutionary speaking, the hair has a beneficial purpose otherwise it would have long disappeared. Medically speaking, hair does indeed serve a purpose- there are several resources you can look at- Google it. Underarm hair draws out sweat as a wick. Eyelashes protect the eyes. Facial hair is a secondary sexual characteristic, it also serves a purpose in keeping the skin safe, the neck and face cool in summer (sweat wick) and warm in winter (layer). Scalp hair protects the scalp, it keeps the head warm (important even when in a warm climate), it draws out the sweat, it acts as a sexual characteristic during foreplay (with your married partner). Hair loss and problems with hair are an early warning sign of health problems such as hormonal imbalance, lack of essential vitamins etc. No hair, no signs.
3. There is anecdotal evidence to suggest that uncut hair (and beards in men) has a role to play in meditation in directing 'spiritual energy'. All great yogis and Rishis have had uncut hair. Buddhists monks shave their heads as they believe such 'energy' is distracting as their form of meditation involves 'directed energy' rather than 'dissipated energy'.
4. See this video;
5. Although you may dismiss this as pseudo-science, but I am in touch with my hair, I can feel it and when I used to have my hair cut before, I felt the pain of it's loss (not for religious reasons). With my hair I now feel complete. With long natural hair, I feel some odd sensation of internal peace.
6. All the religious stuff others have mentioned (please try and take it seriously- read the relevant Gurbani for yourself- but remember that Nanak has said that doing something as a religious ritual serves no purpose- you should be convined of the reasons).

Good luck.

If you cut your hair, it will grow back because it is supposed to be long. It's part of the bana of a human being. Just like stripes are part of a Zebra's bana, or tusks are part of a elephant's bana.

Why do you cut your nails then?

your nails are dead cells when you cut em dude.

The fingernail is formed from the cells located in the growth plate called the epithelial cells. There are three types of epithelial cells: squamous, cuboidal, and columnar. As these cells age they are pushed outward by newly generated epithelial cells at the base of the nail in the growth plate. These cells that have been pushed forward, in the never-ending process, eventually die, allowing the inside of the cell to be taken over by the hard protein keratin which is why our fingernails are so hard and constantly growing.

Guru Gobind Singh Ji says" Bina Shastr Kesun Narun Bhedh Jaano", "Bina Tegh Kesun Divo Na Deedare".
Without weapons and Hairs, a person is like sheep and without them Guru Ji would never give His divine darshan to such a person.

Uncut hair is an unspoken and fly symbol of solidarity with your Sikh brothers and sisters worldwide. It's about love. It's a funky fresh natural organic thing. It's about being true. It's about style and panache. It's about rebelling a little bit against the sweeping pressure of society to conform in every way, physically AND mentally. It can be about consciously proclaiming your identity to be sovereign, beyond the influences of all the bs flying us from every billboard and tv screen telling us what to buy and who to be.

It always was, and today still is about not bowing down to "the man." And yes, It is definitely sexy too. It just is. But if you haven't experienced these things, or don't want to, and have no love for it, then I guess do what you have to, and slip into the tide of conformity. The queue starts at the back, and it is very long. But please, no need to rationalize things to death in an attempt to make yourself comfortable with something. Who are you really trying to convince?

Are you being intellectually honest?

Not wanting to "objectify" what you believe? Aren't you doing that by cutting your hair too? I could respond to your other points, but it wouldn't matter. I personally don't find your reasons very compelling at all, but what matters is you.

to merge with guru-parmeswar, we must be in puran saroop, because thed jort is puran.

puran = mentally, emoionally, and physically puran.

then spiritually full, (puran), is recieved with naam simran.

There isn't one.

Keeping your hair uncut was demanded during times of war to maintain your idnetity. IT's not revelant to this world.

This world is full of lies. Be wary. Honesty is your only means of telling truth from fiction.

God won't be mad at you if you cut it, nor will he be happy if you grow it out. We keep it long because we prefer His roop over the latest "fashion trends".

you need to lose the ego in order to meet God. the only way to lose the ego is to give the head to the Guru. that means we accept the Guru's way of thinking, and that includes keeping the hair. i've been through this whole process of doubts that you guys are going through. trust me, once you take amrit and walk the path (while continuously going to satsangat), your whole mindset will change and you will not only realise the mahaan kirpa of kesh, but wish that you had taken amrit earlier in life.
by the way, bhagti is stored in the kesh
