Using a box dye is much cheaper than going to a salon, much more discreet, and if you know what you're doing, can be just as effective. The trick is to follow the instructions exactly, have a steady hand, and be patient.

It is highly recommended, though not entirely required that you use some simple tools: a rattail comb, a couple alligator clips, and a hair application brush can help you to be much more precise with your dye job.

Before you start, test a small amount of hair dye on a small patch of skin to ensure that you are not allergic to any of the ingredients. Also, it is best to not wash hair for a couple days prior so that small amounts of oils can build up in your scalp and protect your hair from damage.

On the big day, separate your hair into sections, using the end of the rattail comb to separate, and then securing with alligator clips.

Then, mix the hair dye and developer according to the manufacturer's instructions. Make sure you follow the instructions exactly or you could do more damage than good.

Then, using the hair application brush, apply the hair dye to your grey hairs and let sit as per the manufacturer's instructions. Rinse out until the water runs clear and follow with shampoo and conditioner.

Pushing is the first and most important skill to learn on a skateboard. Here is a step-by-step process.

Tomatoes don’t last long on the shelf so freezing them is the ultimate solution. For days when you’ll be busy and won’t have a lot of time to crush or blend them, chop, blend and freeze the tomato puree.

I usually need tomatoes to make pasta sauce, pizza sauce, or tomato soup. So, I blend the tomatoes and freeze them in plastic cups to use later. Slice them into smaller pieces and add them to the blender. Blend until it turns into a smooth paste. Pour it into the extra mugs that you don’t use a lot and cover with plastic wrap and freeze. By defrosting a single cup, you’ll be able to make pasta sauce later. Choose the right size cup or fill it according to your need. 

As the name suggests, the reverse martingale strategy is the opposite of the martingale roulette strategy. Increase your bets when you win, and lower them when you lose. The idea here is to capitalize on hot streaks and keep your losses to a minimum. This strategy is as risky as it is rewarding as if you lose, you can lose most of your entire earnings in one go as well.
