Benefits of Castor oil for hair
http://hairlyobsessed.blogspot.com/2011/01/benefits-of-castor-oil.html
Since my hair is loving castor oil so much right now, I thought I'd post some of the benefits of this oil:
Castor Oil is derived from the castor bean, and seeds of the castor plant. It has been used for decades as a laxative, a purgative (to induce vomiting) and as a skin softener.
The anti-bacterial and anti-fungicidal properties of Ricinoleic Acid in castor oil protects the scalp and hair from infections which can cause hair loss. Castor oil has omega-9 fatty acids in it that prevents your scalp from drying out and that also nourishes your hair from the roots. Castor oil is a humectant as it draws moisture into the hair and skin. Applying castor oil on hair will keep it looking soft, shiny and strong.
Castor oil coats the hair shaft and smoothes the cuticle layer, sealing in moisture and leaving the hair feeling soft and silky. It is more easily absorbed by the hair, allowing for deeper penetration into the hair shaft. Rubbing castor oil into your scalp and roots on a regular basis helps lost hair grow back and also helps thicken hair that’s already growing. You can also experiment with castor oil for hair on your ends. This rich, thick oil will help your ends becomes shiny and hide the appearance of frizzy, damaged, and split ends. Over time, as you trim damage away, you'll notice your hair won't develop split ends as easily.
Castor oil can be used in several different ways for hair:
• As a leave-in.
• Combined with other ingredients to make your conditioner or moisturizer.
• As a pre-poo or hot oil treatment.
As with any hot oil treatment, it is important to avoid overuse of castor oil, especially if you are prone to oily scalp and hair conditions. For hair that is damaged, a hot oil treatment is typically indicated as a monthly treatment, while weekly moisturizing treatments are more useful to restore the good condition to the hair. Since my hair is fine, I have to be careful not to use too much. Otherwise, hair becomes extremely oily and stiff.
Castor oil also thickens eyelashes and eyebrows.
I’ve been rubbing a little castor oil over the base of my eyelashes before bed. This should prevent thinning and promote rapid growth, leading to thicker and fuller lashes. Many commercial products for eyelashes actually contain castor oil. If you want to thicken sparse eyebrows, rub a little castor oil over the brow line before bed.
Here are some non-hair benefits of castor oil:
*Softens thick calluses and removes corns
*Cures skin infections like athlete’s foot and ringworm
*Prevents stretch marks
*Removes moles and warts
*Removes age spots (liver spots)
*Cures acne
*Keeps the skin looking smooth, youthful and unlined
*Breaks up external and internal scar tissue, and prevents new scars from forming
*Soothes shingles

When learning to use oil to condition hair, sorting out what oil to use can be rather confusing. Some people swear by one oil for their hair while others claim that the same oil is terrible for their hair and they will claim another oil as their holy grail of oils.
There is also the issue of oils for the scalp vs. oil for the hair. Not every oil that is good for your hair, is necessarily the best oil for massaging your scalp - although it can be.
Let me briefly tell you what I know about massage oil. I believe the main criteria for a good scalp oil would include an oil that is noncomedogenic, readily absorbed into the skin and of course would take into consideration personal allergies and skin sensitivities. Here are some of the more common skin/massage oils.
Oils said to be good for skin:
almond
avocado
castor oil
coconut
grape seed
jojoba
olive
seabuckthorn
sesame
sunflower
While castor oil is supposed to be very nice for the scalp it is rather thick so it is better to thin it with a lighter weight oil when using it for a scalp massage.
But where things get really confusing for many people is when oil is used to condition the hair after it has left the scalp area. Generally oil for conditioning is used on the very ends of the hair or from the ears down since the hair closer to the scalp doesn't often need as much help from extra oil unless it's been stripped. But people will oil the entire length of the hair as a pre-shampoo conditioning treatment.
This is where it gets tricky and not everybody agrees on what is the best oil for hair. I believe this is because of different hair types and what we hope the oil will do for our hair. So in order to shed some light on this situation and help you to figure out what oils might be good choices for you I'm sharing just a bit of oil/hair science I found a while back.
Coconut oil is one of the most touted hair oils you will hear about. Coconut oil is said to help prevent protein loss when washing hair. This makes it a good oil to use in your hair as a pre-shampoo treatment. Coconut oil is one oil that is proven to penetrate the hair shaft. To give it time to 'do it's thing' most people use it as a pre-treatment for an hour or more, sometimes even applying it the night before.
As far as different oils working better for different hair types, I believe much of this difference has to do with how the different oils work on the hair. Some oils penetrate the hair shaft and other oils sit on top. A while back I compiled a list of oils and classified them as to which oils penetrated and which oils sit on top of hair.
Straight chain glycerides are oils that penetrate:
Avocado
Camellia
Castor Oil
Coconut
Olive
Palm Kernel
Sweet Almond
Oils that partially penetrate:
Meadowfoam seed
Polyunsaturated oils sit on top of hair:
Broccoli Seed
Grapeseed
Jojoba
Sesame
Sunflower
So my theory is that if you are looking for an oil to fortify the hair strand, then choosing one of the penetrating oils is what you will want to try. If you are hoping to seal moisture in or keep humidity out, then I believe choosing one of the oils that coats the hair shaft is a better choice for you. If you are looking to do both, then a mixture of oils from both classes of oils is what you would want to experiment with. Or using a light amount of penetrating oil first and then following with a light amount of an oil that coats the hair.
I also think that whether the hair is damp or dry when you apply the oil also need to be considered. When the hair is damp, after freshly washing, the cuticle is still raised bit. I wonder if this doesn't help the oils that penetrate to get into the hair shaft since the cuticle is already a bit more open. So when you experiment with the best routine for your hair, also factor in how your hair responds to damp oiling vs. dry oiling.
