Cells: The Building Blocks of Life

The human body contains millions of cells that rely on healthy nutrition like proteins, vitamins and minerals. While the body can create some of these nutrients, it also requires essential vitamins and minerals from food sources.
Every living organism depends on its cells to function normally. Often referred to as “the building blocks of life,” cells are the biological, structural and functional units that carry out tasks in an organism. A collection of cells working together is called a tissue, while a series of tissues performing organized functions are called organs.
The human body contains trillions of cells, all with varying tasks that help support bodily organs; these include skin cells, nerve cells, blood cells, barrier function cells (supporting the lungs, gut) and more. Cells rely on good nutrition for energy production and to prevent oxidative damage.
The anatomy of a cell 
Cells in the human body are so tiny that they are invisible to the naked eye–cells range in size from 1 to 100 micrometers. Even the largest type, the fertilized egg, requires the use of a microscope to see. They also have differing lifespans depending on their type and function: Some digestion-related cells can live for a few days while pancreatic cells can live up to a year.

The human body’s cells are made up of the same basic structural parts, even though they may carry out different functions all over the body. Here are the main parts of a cell:
<ul>
<li>Cell membrane: The semipermeable membrane surrounding the cytoplasm of a cell. Contains receptors that identify the cell to other cells and allow some substances through while keeping others out.</li>
<li>Nucleus: The central part of the cell that contains genetic material (DNA) and is enclosed in a membrane; controls cell division and reproduction</li>
<li>Cytoplasm: The thick substances between the cell membrane and the nucleus, containing the cytosol, organelles, cytoskeleton and various particles, that consume and transform energy and perform the cell’s functions.</li>
<li>Mitochondria: Tiny structures inside every cell that provide the cell with energy.</li>
</ul>
Healthy vs. unhealthy cells 
If you were to look at two cells–one healthy and one unhealthy—under a microscope, you might notice that the healthy cell has an intact, sharp outline of the cell membrane and its inner parts (the nucleus and cytoplasm) are clearly defined. An unhealthy cell, on the other hand, would look swollen, have a blurry outline of the cell membrane and its insides would be misshapen. A healthy cell is able to carry out its normal function by producing clean energy and efficiently ridding itself of waste, while an unhealthy cell cannot produce clean energy or cleanse itself of toxins.
Healthy cells become damaged when there is an imbalance of free radicals and antioxidants in the body. This imbalance is called oxidative stress. Toxins enter the body from varying factors, causing free radicals to penetrate into the cell and cause damage to all its components, including proteins, fats and DNA. The damaged cells are associated with signs of aging, affecting the brain, skin and other organs in the body.
Some factors that could contribute to oxidative stress include:
<ul>
<li>Stress (including physical, mental or emotional)</li>
<li>Poor diet (including processed, high fat, high glycemic foods)</li>
<li>Inadequate exercise</li>
<li>Smoking</li>
<li>Environmental contaminants (air and water pollutants, soil contaminants)</li>
</ul>
Cells actually have a self-destruct mechanism within a process called apoptosis. But when apoptosis isn’t working properly, cells can become cancerous and spread to other parts of the body. <a href="http://www.ncbi.nlm.nih.gov/pmc/articles/PMC2724665/">Studies</a> show that an imbalanced metabolism is a precursor for neurodegenerative diseases such as Alzheimer’s and Parkinson’s as well as many other neural conditions.
The Best Nutrients for Your Cells 
In order to produce energy to carry out their tasks and also protect your DNA from free radical damage, your cells need important nutrients. Let’s take a look at a few nutrients and how each specifically helps your cells.
<ul>
<li>Proteins are macronutrients found around the cell, inside the cell and on the cell membrane. Outside of the cell, proteins are part of your bones and soft tissue and help maintain their structures. Inside the cell, proteins act as enzymes responsible for energy production, help protect the cell from DNA damage caused by oxidative stress and, with fats, constitute the structural support of the cell membrane. Proteins that support the cell membrane are vital for the normal functioning of the whole body, helping communicate messages between cells and providing attachment sites where cells can connect with surrounding structures (example: bone cells attach to the bone matrix via proteins on the cell membrane). 
Good food sources: green peas, quinoa, pumpkin seeds, almonds, legumes, whole grains</li>
<li>B vitamins are water-soluble nutrients that support the energy production of cells. Research shows that B vitamins, such as B1, B2, B3, B5 and B6, have specific roles in the mitochondria to support energy metabolism, that is, how your cells break down nutrients into energy your cells can use throughout the body. 
Good food sources: whole grains, beans, potatoes, bananas</li>
<li>Omega-3 fats build and support the cell membrane and affect the function of cell receptors, which help create hormones that help with blood clotting, contracting and relaxing of artery walls and inflammation. These fats also bind to receptors in cells that help to regulate genetic function, which may be why those with diets high in omega-3s are linked to a lower risk of heart disease and stroke, as well as increased protection against some forms of cancer. 
Good food sources: flax seeds, walnuts, chia seeds, fish oil</li>
<li>Vitamin E is a powerful antioxidant that protects the fat and protein components in the cell membranes from oxidative damage. Because of its ability to combat free radicals, vitamin E may help protect against heart disease, cancer and eye disorders. Studies also show the importance of vitamin E in brain function: a healthy intake of the nutrient can prevent or slow the rate of cognitive decline as the brain ages. 
Good food sources: sunflower seeds, almonds, spinach, avocado, extra virgin olive oil</li>
<li>Vitamin C plays an important role in keeping the cell membrane and mitochondria healthy by recycling vitamin E back to an active form. As mentioned above, vitamin E is an extremely vital source of antioxidants that help keep cells healthy. Vitamin C is also vital to your immune system. Your white blood cells contain high levels of vitamin C to kill bacteria and disable viruses by literally eating them up (phagocytosis). 
Good food sources: citrus fruits, pineapple, bell peppers, berries, Brussels sprouts, broccoli, kale and other leafy greens</li>
</ul>
Food is energy, literally. Healthy nutrition goes straight to the cells of your body to help maintain normal functioning and protect your body from toxins. The Hallelujah Diet is a plant-based diet that helps ensure you get the nutrients your body needs to promote overall health by accessing your own body’s healing abilities. Nutrients like protein, healthy fats and antioxidants can rejuvenate your cells and give you the energy your body needs.

Should You Buy an Existing Salon?

After you have completed your cosmetology education and gotten some experience under your belt, you might buy your own salon. Many cosmetologists purchase existing salons to build the business quickly, but you have a lot to think about before you do this. Take caution and consider these factors before signing a contract.
Profitability
Before you buy an existing salon, ask for statements prepared by an accountant displaying at least two year’s worth of financial information. If the reports show the business is not profitable, you need to know why before you decide whether to go through with a purchase.
<div style="width: 610px" class="wp-caption aligncenter"><img alt="Woman having a scalp massage." class="fr-fil fr-dib" height="400" src="https://www.mediashower.com/img/1A29CE9A-800C-11E8-9376-D4B2B477A3F6/bigstock-Spa-woman-Massage-Face-Massag-198632788_600x.jpg" style="width: 600px;" width="600" />
Whether you specialize in spa services or makeup application, the right location makes a difference.
</div>
You should also be able to glean the point at which you will break even each month based on financial reports. Examine revenue and expenses associated with the salon to determine what steps you need to take to see a profit.
Staffing
Buying an existing salon might mean the business comes with staff members in tow. Get to know the individuals working at the salon and if any staff needs to be let go, ensure that you follow local and federal law pertaining to employee termination. If the salon is part of a franchise, you may want to have human resources professionals to guide you.
Business Model
While you are pursuing cosmetology education, you might think about whether you would like to run a franchise or an independently-owned salon. While owning a business is fantastic with creative freedom, operating a franchise allows you to garner support for operations and marketing.
Only you can decide which business model is right for you, but talking to other salon owners and a <a href="https://www.nolo.com/legal-encyclopedia/do-you-need-a-business-lawyers.html" rel="noopener noreferrer" target="_blank">business lawyer</a> can help you carefully analyze the pros and cons of each type of salon.
Location
Even if you offer the best salon services, a bad location cannot do you any favors. The <a href="https://www.entrepreneur.com/article/236746" rel="noopener noreferrer" target="_blank">location should be convenient for customers</a>, optimally allowing for some foot traffic besides appointments. In addition to welcoming foot traffic, you should also assess the location to determine if any changes to the area are coming. What should you expect in terms of potential clientele? Can you do anything to create a more welcoming location?
<div style="width: 610px" class="wp-caption aligncenter"><img alt="Beauty salon." class="fr-fil fr-dib" height="534" src="https://www.mediashower.com/img/1A29CE9A-800C-11E8-9376-D4B2B477A3F6/bigstock-Salon--916983_600x.jpg" style="width: 600px;" width="600" />
Buying an existing salon allows you to build a home where you feel comfortable fulfilling your passion.
</div>
Potential for Success
You cannot make a thoughtful decision without first assessing why the business is available. Was the prior owner bad at marketing? Is the current staff not up to par? Does the interior need a redesign? Factor all of this into your analysis to determine if buying the existing salon is a wise choice. The financial aspects of running a business are important, but so are these often overlooked features.
Part of your cosmetology education includes learning how to be professional in addition to building cosmetology skills. Are you ready to learn more before buying a salon? Check out our <a href="http://beautyce.com/cosmetology-barber-nail-tech/?__mscta=184_70957_3679">cosmetology courses</a> to learn more about skills that help you run a thriving business.
