One of the most recommended Hair Growth Supplements is Viviscal. This supplement is made in Scandinavia, and contains silica, fish proteins, and Vitamin C. It's been shown to help some people thicken out their hair if it is thinning if taken once or twice a day. Within six months your hair can be as thick or even thicker than it was before you started used it. Biotin, which is a B vitamin, can help with thinning hair and also with fragile nails. It's water soluble which means your body can excrete out the excess, so nothing builds up in your system. There are mixed results with biotin and hair regrowth; however there are no side effects, so it's always worth a shot.

If your vitamin D levels are low, your hair regrowth cycle may be diminished. Taking a vitamin D supplement can help bring your levels back to normal and bring your growth cycle back in to full swing. A small study has shown that around 60% of patients that have taken saw palmetto extract have had improved hair growth after taking the supplement regularly. Saw palmetto is an extract from the American dwarf pine tree.

Some success has also been had with hair growth activation spray. Sometimes you can get activation drops put in to shampoo, or put through conditioner, to help promote hair growth when washing your hair. When working with activation drops, you drop them on to your scalp and wait for it to dry, and then spray the activation spray to let it soak in to the skin. There are also activation sprays available that you apply as a conditioner and then blow dry it in to your hair.

Hair growth can become impaired because of collected body toxins. Therefore many supplement recipes use vitamin A, which is a confirmed anti-oxidant. While vitamin A is very important vitamin for your body, it's key not to take too much. Vitamin A is fat soluble so excess will get absorbed in to the body and can cause liver damage. Castor oil can be thinned out with another oil or used on it's own, and when massaged in to the scalp, helps to promote blood flow to the scalp area. This has been shown to help promote hair growth, and if you use Jamaican black castor oil, the ash from the slow roasted beans can also help with hair growth.

If your hair is thinning or has lost the volume it once had, there are several steps available to you. Taking some supplements and vitamins can help bring your hair back to it's old luster, and even make it better than it used to be. You might have to be careful with certain supplements, but generally they have no side effects and are always worth a shot.
