Are Eggs Good for Hair Growth?

Partly: eggs can support normal hair growth when they help you meet your protein and biotin needs, because hair follicles need these nutrients to make hair.

Are eggs good for hair growth?

Eggs can be a useful part of a balanced diet, particularly if your usual diet does not provide enough protein or biotin. For a broader look at nutrition, see our guide to the best foods for hair growth. Eating eggs does not guarantee faster growth or reverse hair loss.

The distinction matters: supplying a missing nutrient can help restore normal hair growth, but extra nutrients do not necessarily improve growth when your needs are already met. Hair shedding can also have causes unrelated to diet, so eggs are not a substitute for finding out why hair is falling out.

How could eggs support hair growth?

Hair is made primarily of keratin, a protein. The body needs protein from food to build and maintain tissues, including hair, and an inadequate protein intake can affect normal hair growth. Both egg whites and yolks provide protein.

Egg yolks also contain biotin, a vitamin involved in normal metabolism. Biotin deficiency can cause hair loss, although deficiency is uncommon. Eating eggs as part of a varied diet can contribute biotin; it does not follow that extra biotin will improve hair growth in someone who already gets enough.

There is an important difference between cooked and raw eggs. Raw egg whites contain avidin, a protein that binds biotin and can reduce its absorption. Cooking reduces avidin’s biotin-binding activity and also makes eggs safer to eat.

Adequate hydration supports general health, but hydration alone is not a proven way to speed hair growth; see the best drinks for hair growth.

What does the evidence say about eggs and hair growth?

The direct evidence for this question is limited. A 1981 case report described a child who developed biotin deficiency and complete hair loss while following a diet containing raw eggs. After biotin treatment and removal of raw eggs from the diet, the reported problems resolved.

This case shows why the form of eggs matters: repeated consumption of raw egg whites contributed to the deficiency rather than supporting hair growth. It does not show that eating cooked eggs makes hair grow faster. The child received both biotin treatment and a dietary change, so the report cannot establish the effect of either change alone.

A single case report is much weaker evidence than a randomized trial. No clinical trial comparing cooked eggs with no eggs for hair growth is included in the evidence reviewed here. It is therefore reasonable to view eggs as a source of useful nutrients, not as a proven hair-growth treatment.

How should you use eggs for hair growth?

Eat fully cooked eggs as one part of a balanced eating pattern that supplies enough protein and overall energy. For example, choose hard-boiled eggs or scrambled eggs cooked until firm. Cook both the whites and yolks thoroughly, and avoid consuming raw eggs for a supposed hair benefit.

You do not need to rely on eggs as your only protein source or eat them on a particular schedule. A varied diet can help you meet nutrient needs without assuming that any one food will determine how your hair grows. If your diet is restricted or you suspect you are not eating enough, a registered dietitian can help you assess it.

Applying an egg mask to the scalp is not supported by the evidence reviewed here as a way to grow hair. Raw egg can also contaminate surfaces and may cause a reaction in someone with an egg allergy. Eating safely prepared eggs is the more practical way to obtain their nutrients.

Who should be careful, and when should you see a doctor?

Avoid eggs if you have an egg allergy, and ask a clinician or dietitian about suitable alternatives. People who are pregnant, young children and others at higher risk of foodborne illness should be especially careful to eat eggs thoroughly cooked. If you have high cholesterol or heart disease, ask your clinician how eggs fit into your overall diet.

See a healthcare professional if hair loss is sudden, patchy, persistent or accompanied by scalp pain, redness or scaling. Seek advice for a child’s hair loss as well. A clinician can assess possible causes, which may include a nutrient deficiency, thyroid condition, illness or medication effect; do not stop prescribed medication on your own.

Ask before taking a biotin supplement for hair loss. High-dose biotin can interfere with some laboratory test results, and more biotin is not necessarily helpful if you are not deficient. Tell your healthcare team about any supplements you take, especially before blood tests.
